Answer:

The difference lies in the coverage of the construction.  While local level construction focuses on the local area, national level construction has a nation-wide coverage.

Explanation:

Residential construction concentrates on the construction of residential buildings that have sleeping accommodations.  Such constructions are opposed to the construction of other buildings that are meant for commercial uses as they lack sleeping accommodations.  The federal, state, and local governments can embark on the construction of residential quarters for their residents.  The constructions are also funded at the given level.  When it is locally funded, the construction is meant to satisfy specific local needs.  The constructions by the federal government consider the needs of many localities, and may not meet specific local needs.

Answer: A Residential construction is local in its effects even though those effects have a national impact.

Problem 2:A large tubular workpart with an outside diameter of 45 inches and an inside diameter of 25 inches needs to be faced on a lathe. The facing operation will be carried out at a rotational speed of 30 rev/min, a feed rate of 0.020 in/rev, and a depth of cut of 0.150 in. Determine:Cutting time to complete the facing operation.Cutting speeds.

Metal removal rates at the beginning and end of the cut.(a) The cutting time to complete the facing operation is given by the formula as follows:$$t_c=\frac{L}{frn}$$where L is the length of the workpart to be cut, f is the feed rate, r is the depth of cut, and n is the rotational speed.Let us first determine the length of the workpart to be cut. Since it is a tubular workpart, the length of the workpart is given by its circumference, that is,$$L=\pi\frac{(D_o-D_i)}{2}$$$$L=\pi\frac{(45-25)}{2}=31.42 in$$Substituting the values of L, f, r, and n, we get$$t_c=\frac{L}{frn}$$$$t_c=\frac{31.42}{0.020\times0.150\times30}=104.73\ minutes$$Therefore, the cutting time to complete the facing operation is 104.73 minutes.(b) The cutting speeds at the beginning and end of the cut are given by the formula as follows:$$v=\pi D n$$where D is the mean diameter of the workpart. The mean diameter of the workpart is given by,$$D=\frac{(D_o+D_i)}{2}$$$$D=\frac{(45+25)}{2}=35 in$$Substituting the values of D and n, we get$$v=\pi D n$$$$v=\pi\times35\times30$$$$v=3298.15\ in/min$$Therefore, the cutting speed is 3298.15 in/min.(c) The metal removal rate at the beginning and end of the cut are given by the formula as follows:$$Q=\frac{f\times v}{2}$$Substituting the values of f and v, we get at the beginning of the cut,$$Q=\frac{f\times v}{2}$$$$Q=\frac{0.020\times3298.15}{2}=32.98\ in^3/min$$Similarly, the metal removal rate at the end of the cut is,$$Q=\frac{f\times v}{2}$$$$Q=\frac{0.020\times3180.06}{2}=31.80\ in^3/min$$Therefore, the metal removal rate at the beginning of the cut is 32.98 in3/min, and at the end of the cut is 31.80 in3/min.Problem 3:Solve the problem as the previous one, except that the machine tool controls operate at a constant cutting speed by continuously adjusting rotational speed for the position of the tool relative to the axis of rotation.

The rotational speed at the beginning of the cut =30 rev/min, and is continuously increased thereafter to maintain a constant cutting speed.Since the machine tool controls operate at a constant cutting speed, the cutting speed can be calculated by the formula as follows:$$v=C_s\times R_p$$$$v=C_s\times\Delta r\times n$$$$v=C_s\times0.075\times n$$where Cs is the constant cutting speed, Rp is the radius of the tool relative to the axis of rotation, Δr is the change in radius of the tool for each unit change in length of cut, and n is the rotational speed.Since the rotational speed is 30 rev/min at the beginning of the cut, the constant cutting speed can be calculated by substituting the values of Δr, n, and v at the beginning of the cut.$$\Delta r=\frac{(D_o-D_i)}{2L}$$$$\Delta r=\frac{(45-25)}{2\times31.42}=0.075 in$$$$C_s=\frac{v}{\Delta r\times n}$$$$C_s=\frac{3298.15}{0.075\times30}=14662.8\ in/min$$Therefore, the constant cutting speed is 14662.8 in/min.To maintain a constant cutting speed, the rotational speed needs to be adjusted continuously. Let us calculate the rotational speed at the end of the cut. Since the metal removal rate is constant,$$Q=\frac{f\times v}{2}$$$$v=\frac{2Q}{f}$$$$v=\frac{2\times31.80}{0.020}=3180.06\ in/min$$Substituting the values of Cs, Δr, and v, we get$$C_s\times\Delta r\times n=v$$$$n=\frac{v}{C_s\times\Delta r}$$$$n=\frac{3180.06}{14662.8\times0.075}=2.720\ rev/min$$Therefore, the rotational speed at the end of the cut is 2.720 rev/min.

The percent voids between the aggregate particles can be determined using the following equation.

Aggregate is a term used to describe a group of objects or items that have been collected together. In the business world, aggregate often refers to groups of people or data that have been combined in some way. Aggregates can include data from multiple sources, or a combination of different types of data, such as financial or demographic information.

Percent Voids = [(Absolute Unit Weight - Dry-Rodded Unit Weight) / Absolute Unit Weight] * 100

Absolute Unit Weight = Bulk Dry Specific Gravity * 62.4 lb/ft3

For this example, the calculation would be:

[(62.4 lb/ft3 - 72.5 lb/ft3) / 62.4 lb/ft3] * 100 = -15.7%

The negative number indicates that the dry-rodded unit weight is greater than the absolute unit weight and therefore that the voids between the aggregate particles have been reduced.

If the resistance of a circuit is 5 ohms and the current is 5 amps, the power in watts is calculated using the formula P = I^2*R, where P is power, I is current, and R is resistance.

Substituting the given values into the formula, we get P = (5)^2*5 = 125 watts. This means that the circuit is consuming 125 watts of power at any given moment, which is a measure of the rate at which energy is being transferred or transformed. It is important to note that the power consumed by a circuit depends on both the current and the resistance, and increasing either one will result in a higher power consumption. This has implications for the design and operation of electrical systems, as well as for energy efficiency and conservation efforts.

The lift coefficient for each airfoil can be found by using the single vortex method. For a uniform stream with speed V1 at an angle of attack alpha.

A biplane with flat plate airfoils of chord c at a distance h apart, the lift coefficient can be calculated by dividing the total vortex strength by the product of the velocity and the reference area.

The lift coefficient represents the lift generated by an airfoil relative to its size and the flow conditions. In this case, we can use the single vortex method, which simplifies the flow field by representing each airfoil as a single vortex. To find the lift coefficient for each airfoil, we need to calculate the total vortex strength (Γ) for each vortex, and then divide it by the product of the velocity (V1) and the reference area (c). The reference area is the area over which the lift force is evaluated, and in this case, it is the airfoil chord (c). By dividing the total vortex strength by the velocity and reference area, we obtain the lift coefficient for each airfoil.

The amount of torque produced by a motor at the instant the load causes it to stall is called the "stall torque." When a motor operates at its rated voltage and frequency, it is designed to deliver a specific amount of torque to drive the load it is connected to.

Torque is the rotational force exerted by the motor to generate motion or maintain the position of the load. The motor's ability to produce torque depends on factors such as its design, construction, and power supply.

Under normal operating conditions, the motor generates torque that is sufficient to overcome the load and maintain rotation. However, when the load exceeds the motor's torque capability, the motor reaches its maximum torque output, known as the stall torque. At this point, the motor cannot produce enough torque to continue rotating, and it comes to a halt or stalls.

The stall torque is a crucial parameter in motor specifications as it provides information about the motor's ability to handle heavy loads or start-up conditions where a high torque is required. It represents the maximum torque output that the motor can generate when it is unable to overcome the load and maintain rotation.

Motor manufacturers provide stall torque ratings in motor datasheets or technical specifications. It is important to consider the stall torque when selecting a motor for applications where the load demands high starting torque or requires the motor to handle heavy loads without stalling.

The stresses in steel and concrete are 1,631.29 MPa and 0.2535 MPa respectively.

The extension of column due to the load is 0.0017mm

To find the stresses in the steel and concrete, we need to use the principle of stress-strain proportionality. The formula for stress is:

Stress (σ) = Load (P) / Area (A)

The area of the steel rods is:

A = (π/4) * (25 mm)^2 = 490.87 mm^2

The area of the concrete is:

A = (π/4) * (600 mm)^2 = 314,159 mm^2

The stress in the steel is:

σ_steel = P / A = 800 kN / 490.87 mm^2 = 1,631.29 MPa

The stress in the concrete is:

σ_concrete = P / A = 800 kN / 314,159 mm^2 = 0.2535 MPa

To find the extension of the column, we need to use the formula for strain:

Strain (ε) = Extension (ΔL) / Original length (L)

We can use the principle of linear elasticity to find the extension of the column due to the load, which states that:

Stress = Young's modulus * Strain

We can use the formula of stress and strain to find the extension of the column:

ΔL = (PL)/(AE)

L = 600mm, P = 800kN and A =314,159 mm^2

ΔL = (80010^310^-360010^-3)/(314,1592510^9) = 0.0017 mm
