Manager T. C. Downs of Plum Engines, a producer of lawn mowers and leaf blowers, must develop
an aggregate plan given the forecast for engine demand shown in the table. The department has
a regular output capacity of 130 engines per month. Regular output has a cost of $60 per engine.
The beginning inventory is zero engines. Overtime has a cost of $90 per engine.
a. Develop a chase plan that matches the forecast and compute the total cost of your plan. Regular
production can be less than regular capacity.
b. Compare the costs to a level plan that uses inventory to absorb fluctuations. Inventory carrying
cost is $2 per engine per month. Backlog cost is $90 per engine per month. There should not be a
backlog in the last month.
Answers
Explanation:
To develop an aggregate plan, we need to consider the forecasted demand and available capacity while minimizing costs. Let's analyze the two scenarios:
a. Chase Plan:
In a chase plan, the production is adjusted to match the forecasted demand. This means that each month's production will be equal to the demand for that month. However, the regular output can be less than regular capacity.
Using the given regular output capacity of 130 engines per month, we can match the demand as follows:
Month | Forecasted Demand | Production (Chase Plan)
-----------------------------------------
Jan | 150 | 150
Feb | 110 | 110
Mar | 120 | 120
Apr | 140 | 140
May | 160 | 160
Jun | 180 | 180
Total cost for the chase plan:
= (Regular Production Cost + Overtime Production Cost)
= (150 * $60 + 0 * $90) + (110 * $60 + 0 * $90) + (120 * $60 + 0 * $90) + (140 * $60 + 0 * $90) + (160 * $60 + 0 * $90) + (180 * $60 + 0 * $90)
= $9,000 + $6,600 + $7,200 + $8,400 + $9,600 + $10,800
= $51,600
b. Level Plan:
In a level plan, we aim to maintain a constant production rate throughout the planning horizon, using inventory to absorb fluctuations in demand. Backlog should not exist in the last month.
To calculate the optimal production rate, we need to consider the carrying cost and backlog cost. Let's calculate the production rate based on these costs:
Carrying cost = $2 per engine per month
Backlog cost = $90 per engine per month
Total cost for the level plan:
= (Carrying Cost + Backlog Cost)
= (0 * $2 + 40 * $90) + (40 * $2 + 0 * $90) + (10 * $2 + 20 * $90) + (30 * $2 + 0 * $90) + (50 * $2 + 0 * $90) + (70 * $2 + 0 * $90)
= $3,600 + $800 + $2,200 + $60 + $100 + $140
= $6,900
Therefore, the total cost for the chase plan is $51,600, and the total cost for the level plan is $6,900.

Compute the volume percent of graphite, VGr, in a 2.5 wt% C cast iron, assuming that all the carbon exists as the graphite phase. Assume densities of 7.9 and 2.3 g/cm3 for ferrite and graphite, respectively.
Answers
Answer:
The volume percent of graphite is 91.906 per cent.
Explanation:
The volume percent of graphite (\(\% V_{Gr}\)) is determined by the following expression:
\(\%V_{Gr} = \frac{V_{Gr}}{V_{Gr}+V_{Fe}} \times 100\,\%\)
\(\%V_{Gr} = \frac{1}{1+\frac{V_{Gr}}{V_{Fe}} }\times 100\,\%\)
Where:
\(V_{Gr}\) - Volume occupied by the graphite phase, measured in cubic centimeters.
\(V_{Fe}\) - Volume occupied by the ferrite phase, measured in cubic centimeters.
The volume of each phase can be calculated in terms of its density and mass. That is:
\(V_{Gr} = \frac{m_{Gr}}{\rho_{Gr}}\)
\(V_{Fe} = \frac{m_{Fe}}{\rho_{Fe}}\)
Where:
\(m_{Gr}\), \(m_{Fe}\) - Masses of the graphite and ferrite phases, measured in grams.
\(\rho_{Gr}\), \(\rho_{Fe}\) - Densities of the graphite and ferrite phases, measured in grams per cubic centimeter.
Let substitute each volume in the definition of the volume percent of graphite:
\(\%V_{Gr} = \frac{1}{1 +\frac{\frac{m_{Gr}}{\rho_{Gr}} }{\frac{m_{Fe}}{\rho_{Fe}} } } \times 100\,\%\)
\(\%V_{Gr} = \frac{1}{1+\left(\frac{m_{Gr}}{m_{Fe}} \right)\cdot \left(\frac{\rho_{Fe}}{\rho_{Gr}} \right)}\times 100\,\%\)
Let suppose that 100 grams of cast iron are available, masses of each phase are now determined:
\(m_{Gr} = \frac{2.5}{100}\times (100\,g)\)
\(m_{Gr} = 2.5\,g\)
\(m_{Fe} = 100\,g - 2.5\,g\)
\(m_{Fe} = 97.5\,g\)
If \(m_{Gr} = 2.5\,g\), \(m_{Fe} = 97.5\,g\), \(\rho_{Fe} = 7.9\,\frac{g}{cm^{3}}\) and \(\rho_{Gr} = 2.3\,\frac{g}{cm^{3}}\), the volume percent of graphite is:
\(\%V_{Gr} = \frac{1}{1+\left(\frac{2.5\,gr}{97.5\,gr} \right)\cdot \left(\frac{7.9\,\frac{g}{cm^{3}} }{2.3\,\frac{g}{cm^{3}} } \right)} \times 100\,\%\)
\(\% V_{Gr} = 91.906\,\%\)
The volume percent of graphite is 91.906 per cent.

A batch of parts is produced on a semi-automated production machine in a sequential batch production operation. Batch quantity is 300 units. Setup takes 55 min. A worker loads and unloads the machine each cycle, which takes 0.75 min. Machine processing time is 3.46 min/cycle, and tool handling time is negligible. One part is produced each cycle. Determine:
a. Average cycle time
b. Time to complete the batch
c. Average production rate.
Answers
Answer:
a) 4.21 min
b) 21.9666 hrs
c) 1.3657 Pc/hr
Explanation:
Given that;
Batch quantity = 300 units
time setup = 55min
unload/loading time = 0.75
processing time = 3.46
a) Average cycle time;
Average Cycle Time TC = loading time + processing time
TC = 0.75 + 3.46
Tc = 4.21 min
b) Time to complete the batch
Time to complete the batch Tb = setup time + process time + non operation time
Tb = (55min * 1hr/60min) + (300 * 3.46 * 1hr/60min) + (300 * 0.75 * 1hr/60min)
Tb = 0.9166 + 17.3 + 3.75
Tb = 21.9666 hrs
c) Average production rate
Average production rate Rp = 1 / ( Tb / batch size)
we substitute
Rp = 1 / ( 21.9666 / 300 )
Rp = 1 / 0.7322
Rp = 1.3657 Pc/hr
What is the process that a ceramist uses to knead and remove pockets of air from wet clay?
A. throwing
B. slabbing
C. coiling
D. wedging
Answers
The process that a ceramist uses to knead and remove pockets of air from wet clay is called wedging.
Wedging involves a technique of working the clay by hand to remove any air bubbles or inconsistencies in the clay's texture. The ceramist takes a lump of wet clay and repeatedly kneads, compresses, and folds it to ensure uniformity and eliminate air pockets. This process helps to improve the clay's plasticity, remove excess moisture, and create a more workable and consistent material for shaping and forming. Wedging is an essential step in the preparation of clay before it can be used for various ceramic techniques such as throwing, slabbing, or coiling. It ensures that the clay is free from air bubbles that could cause structural weaknesses or uneven drying during the firing process.

θ₁ = 10°
3. In the same question, what is the value of B?
B = 60
4. In the same question, what is the value of θ2 in degrees?
θ₂ = 5°
Explanation:
The output signal Vout(t) is in the form
Vout(t)=Acos(200πt + θ₁) + Bcos(400πt + θ₂)
The input signal Vin(t) is given as
Vin(t) = 10cos(200πt + 30°) + 20cos(400πt + 45°)
The output signal Vout(t) is found by
Vout(t) = H(f) × Vin(t)
Where H(f) is the transfer function at various frequencies and Vin(t) is the input signal.
H(200) = 1 ∠−20°
H(400) = 3 ∠−40°
converting the input signal into phasors
10cos(200πt + 30°) = 10 < 30°
20cos(400πt + 45°) = 20 < 45°
Vout(t) = H(200)×10cos(200πt + 30°) + H(400)×20cos(400πt + 45°)
Vout(t) = (1 ∠−20°)×10cos(200πt + 30°) + (3 ∠−40°)×20cos(400πt + 45°)
Vout(t) = (1 ∠−20°)×(10 < 30°) + (3 ∠−40°)×(20 < 45°)
Multipy the magnitude and add phase angles together
Vout(t) = (1×10 ∠−20° + 30°) + (3×20 ∠−40° + 45°)
Vout(t) = 10 ∠ 10° + 60 ∠5°
Vout(t) = 10cos(200πt + 10°) + 60cos(400πt + 5°)
Comparing it with the general form
Vout(t)=Acos(200πt + θ₁) + Bcos(400πt + θ₂)

three boards, each 50 mm thick, are nailed together to form a beam that is subjected to a 1200-n vertical shear. knowing that the allowable shearing force in each nail is 600 n, determine the largest permissible spacing s between the nails.
Answers
Answer:
The cross-sectional area of the beam is 50 mm x 150 mm = 7500 mm². The shear stress in the beam is:
τ = V/A = 1200 N / 7500 mm² = 0.16 N/mm²
The total cross-sectional area of the three nails is:
A_nails = 3 x π/4 x d² = 3 x π/4 x (5 mm)² = 58.9 mm²
The shear stress in each nail is:
τ_nail = τ x A / A_nails = 0.16 N/mm² x 7500 mm² / 58.9 mm² = 20.4 N/mm²
The maximum permissible force in each nail is 600 N, so the maximum permissible stress in each nail is:
σ_nail = F_nail / A_nail = 600 N / 58.9 mm² = 10.2 N/mm²
The maximum permissible shear stress occurs when all three nails are carrying the same load, so the total force on the nails is 1200 N. The maximum permissible spacing between the nails is:
s = L / (n-1) ≤ (σ_nail / τ_nail) x d
where L is the length of the beam, n is the number of nails, and d is the diameter of each nail.
For safety, we want to use a spacing that is less than or equal to the maximum permissible spacing:
s ≤ (σ_nail / τ_nail) x d
Substituting the given values, we get:
s ≤ (10.2 N/mm² / 20.4 N/mm²) x 5 mm = 2.5 mm
Therefore, the largest permissible spacing s between the nails is 2.5 mm.

When working with multiple ground glass joints in a set-up, when should you apply grease to the joints?.
Answers
When working with multiple ground glass joints in a set-up, the time that you should apply grease to the joints is if the reaction is said to to be at a heated point that is above 150 oC, or, when the joints required is still rotated if in use.
Why are grease joints in ground glass used?Despite being made to fit together relatively nicely, ground glass joints are not completely airtight. In certain circumstances, grease must be applied to each joint to make sure of a good seal (such as when employing lower pressure inside an equipment).
Note that In ambient lighting, ground or frosted glass is frequently used as a heat- and weather-resistant light diffuser, particularly on the glass covers or enclosures for lamp fixtures and occasionally on incandescent bulbs.

A cylindrical tank is required to contain a gage pressure 670 kPakPa . The tank is to be made of A516 grade 60 steel with a maximum allowable normal stress of 150 MPaMPa . If the inner diameter of the tank is 2 mm , what is the minimum thickness, tt, of the wall
Answers
Answer:
The minimum thickness t of the wall is 0.00446 mm
Explanation:
Solution
Given that
Pressure =670kPa = 0.670
σ allowable normal stress = 150 MPa
Inner diameter = 2mm
Steel = A516 grade 60
Now,
Since the hoop stress is twice the longitudinal stress, the cylindrical tank is more likely to fail from the hoop stress.
Thus
σ allowable = σₙ = pμ/t
=p (d/2)
150 MPa =0.670MPa * 2/2/t
=0.67/t
t=0.67/150
t =0.00446 mm
a temporary combustible structure should never be placed closer than
Answers
A temporary combustible structure should never be placed closer than 10 feet to a building or property line. A temporary combustible structure is a type of structure made up of combustible materials that is put up for a brief period of time.
These structures are not meant to last for an extended period of time, and they can be disassembled quickly when the need arises. As a result, temporary combustible structures have a wide range of applications, including outdoor events, construction sites, and other short-term applications.
The temporary combustible structure should not be put closer than 10 feet to a building or property line, as stated by the National Fire Protection Association (NFPA). This is to prevent fires from spreading and causing harm to the adjacent structures.
When designing a temporary combustible structure, it's important to think about fire safety. To keep the structures secure and minimize the danger of fires, the following measures must be taken into consideration:
Ensure that the materials used to build the structure are fire-resistant. Use fire extinguishers to help keep fires at bay.Make sure that all exits are clear and that the means of egress are adequate. Make sure that all wires and cables are properly insulated, secured, and far from combustible materials.
Ensure that the fire department has access to the site and can easily get to the structure if necessary. These steps can assist in making sure that temporary combustible structures are safe and do not pose a danger to people or the surrounding environment.
