Theresulting composite bar is subjected to an axial compressive load of 1000 kN. If the bar and cylindercontract by the same amount, calculate the stress in each. The temperature of the compressed compositebar is then reduced by 150Cbut no change in length is permitted. Calculate the final stress in the bar and the cylinder if E(steel)= 200,000 N/mm^2, E(aluminum)= 80,000 N/mm^2, coefficient of linear expansion for steel= 0. 0000012/C and coefficient of linear expansion for aluminum= 0. 000005/C
According to the question: the Stress in cylinder is 1813 N/mm^2.
What is cylinder?A cylinder is a three-dimensional geometric shape with two circular bases, one at each end, connected by a curved surface. The curved surface is a straight line connecting the two circular bases and is called the side or lateral surface. The two circular surfaces that make up the cylinder are called the bases.
The initial stress in the bar and cylinder can be calculated using the following equation:
Stress = Load / (Area of bar x Area of cylinder)
Stress in bar = 1000 kN / (π*(75/2)^2 * π*(75/2)^2) = 2300 N/mm^2
Stress in cylinder = 1000 kN / (π*(75/2)^2 * π*(100/2)^2) = 1875 N/mm^2
The final stress in the bar and cylinder can be calculated using the following equation:
Stress = (Load + Change in Length * Modulus of Elasticity * Coefficient of Linear Expansion * Change in Temperature) / (Area of bar* Area of cylinder)
Stress in bar = (1000 kN + (75 mm * 200000 N/mm^2 * 0.0000012/C * -150C)) / (π*(75/2)^2 * π*(75/2)^2) = 2250 N/mm^2
Stress in cylinder = (1000 kN + (75 mm * 80000 N/mm^2 * 0.000005/C * -150C)) / (π*(75/2)^2 * π*(100/2)^2) = 1813 N/mm^2

During this process the piston is lifted and to height of 10cm by Nitrogen gas. The initial pressure and temperature of argon are 300K and 1 bar. The final temperature of argon gas is 320K for argon R = 0.208 kJ/kgK and r = 1.67 Find the net work done by the Nitrogen
The net work done by the Nitrogen in lifting the mass and the pressure is; W_n = 0.6257 kJ
What is the net work done?We are given;
Mass of argon; m_a = 0.1 kg
mass of piston; m_p = 5 kg
Pressure 1; p₁ = 100 kPa
Temperature 1; T₁ = 300 K
Temperature 2; T₂ = 320 K
Ideal gas constant; R = 0.208 kJ/kg.K
γ = 1.67
Since the reaction is adiabatic and slowly reversible, then we will use the formula; PV^(γ) = C
Thus, work done by argon is;
W_ar = [m_a * R(T₁ - T₂)]/(γ - 1)
W_ar = [0.1 * 0.208(300 - 320)]/(1.67 - 1)

During one eight-hour shift, 750 non-defective parts are desired from a fabrication operation. The standard time for the operation is 15 minutes. Because the machine operators are unskilled, the actual time it takes to perform the operation is 20 minutes, and ,on average, one-fifth of the parts that begin fabrication are scrapped. Assuming that each of the machines used for this operation will not be available for one hour of each shift, determine the number of machines required.
Answer:
No. of Machines Required = 47
Explanation:
First, we calculate the number of parts that can be manufactured by one machine during the shift. For that purpose, we use following formula:
No. of Parts Manufactured by 1 Machine = Total Operating Time/Time taken to perform Operation
where,
Total Operating Time = 8 h - 1 h = (7 h)(60 min/h) = 420 min
Time taken to perform operation = 20 min
Therefore,
No. of Parts Manufactured by 1 Machine = 420 min/20 min
No. of Parts Manufactured by 1 Machine = 21
Now, we will calculate the no. of non-defective parts manufactured by 1 machine. Since, it is given that one-fifth of the parts manufactured by machine are defective. Therefore, the non-defective parts will be: 1 - 1/5 = 4/5 (four-fifth).
No. of Non- Defective Parts Manufactured by 1 Machine = N = (4/5)(21)
N = 16.8 = 16 (Since, the 17th part will not be able to complete in time)
So, the no. of machines required to produce 750 non-defective parts is given by:
No. of Machines Required = No. of non-defective parts required/N
No. of Machines Required = 750/16
No. of Machines Required = 46.9
No. of Machines Required = 47 (Since, 46 machines will not be able complete the job)
A river has an average rate of water flow of 59.6 M3/s. This river has three tributaries, tributary A, B and C, which account for 36%, 47% and 17% of water flow respectively. How much water is discharged in 30 minutes from tributary B?
Answer:
50421.6 m³
Explanation:
The river has an average rate of water flow of 59.6 m³/s.
Tributary B accounts for 47% of the rate of water flow. Therefore the rate of water flow through tributary B is:
Flow rate of water through tributary B = 47% of 59.6 m³/s = 0.47 * 59.6 m³/s = 28.012 m³/s
The volume of water that has been discharged through tributary B = Flow rate of water through tributary B * time taken
time = 30 minutes = 30 minutes * 60 seconds / minute = 1800 seconds
The volume of water that has been discharged through tributary B in 30 seconds = 28.012 m³/s * 1800 seconds = 50421.6 m³

To determine if the rings are pure silver, we can calculate the density of the rings and compare it to the density of pure silver. The density of a material is the mass of the material per unit volume.
First, we need to find the volume of one of the rings. Since the rings are cylindrical, we can use the formula for the volume of a cylinder to find the volume of each ring:
V = π * r^2 * h
Where V is the volume of the ring, π is approximately equal to 3.14, r is the radius of the ring, and h is the height of the ring. In this case, the height of the ring is equal to the thickness of the ring, which is equal to the change in the water level (8.45 mm) divided by the number of rings (10). The radius of the ring is equal to half the diameter of the graduated cylinder (2.5 cm / 2 = 1.25 cm), since the rings are placed in the cylinder side by side.
Plugging these values into the formula, we find that the volume of each ring is:
V = 3.14 * (1.25 cm)^2 * (8.45 mm / 10) = 0.00367 cm^3
Next, we can use the mass and volume of each ring to calculate the density of the rings:
density = mass / volume
Since the mass of each ring is 0.738g and the volume of each ring is 0.00367 cm^3, the density of the rings is:
density = 0.738 g / 0.00367 cm^3 = 201.09 g/cm^3
Finally, we can compare the density of the rings to the density of pure silver, which is 10.49 g/cm^3. Since the density of the rings is much higher than the density of pure silver, it is likely that the rings are not pure silver.
It is important to note that this calculation is only an approximate estimation of the purity of the rings. There may be other factors that affect the density of the rings, such as impurities or variations in the thickness of the rings. Additionally, the value of the density of pure silver used in this calculation may not be entirely accurate, as the density of a material can vary depending on factors such as temperature and pressure. A more precise determination of the purity of the rings would require further testing and analysis.
