Explanation:
a bushing is to be manufactured from coarse iron powders. it is desired that it have a final density 90% that of cast iron, and it is known that the shrinkage in sintering will be approximately 5%. the bushing is 50 mm in outer diameter and has a 20 mm inner diameter, what is the required press force? hint: percent shrinkage is along a single dimension
Surface is not a factor in the pressing force. Thus, regardless of the press's load, the same force is always applied.
Explain about the press force?A press is nothing more than a flat bed with a mechanically or hydraulically controlled pressing ram or rod. To produce a metal-pressed item, you must insert two halves of a metal press tool into the press. The tool is then bolted to the work surface at the bottom and to the ram or rod at the top
Presses are widely employed to bend or straighten materials as well as to press two items, such as bearings or other metal shaft-fitted components, together or away. Some smaller presses, like C-frame presses, can also be used to keep materials together during assembly or remove sections for maintenance.

Here, it is evident that a square plate requires more time than a cylinder. Therefore, a larger riser will be needed, and there will be a range of sizes for the riser.
We are aware that the time required for solidification equals C(volume/area), where C is a constant.
volume of cylinder = r2h where r = 100mm = 0.1 m and h = 50mm = 0.05 m
Cylinder volume = (0.1)
²×0.05 =0.00157m³
the cylinder's total surface area is equal to 2r² + 2rl (0.1)
Time taken for the cylinder = C(Volume/Area) = C(0.00157/0.0942) = (2.78 10⁻⁴)C since 2 + 2(0.1)(0.05) = 0.0942 m2.
For a square plate, h = 75 mm = 0.075m, l = b = x, and x = 0.144m. Accordingly, l = b = 0.144m, and the volume of the square plate is equal to 0.0157 m³ [A/C to inquiry].
Total surface area is equal to 2 (lb + bh + hl) (0.144)
Time taken for a square plate equals C(volume/area) = C(0.00157/0.0847) = (3.43 10⁻⁴)C because 2 + 4 (0.144) (0.075) = 0.0847 m³

a fatigue test was conducted in which the mean stress was 60 mpa (8702 psi), and the stress amplitude was 230 mpa (33360 psi). (a) compute the maximum stress level. mpa (b) compute the minimum stress level. mpa (c) compute the stress ratio. (d) compute the magnitude of the stress range. mpa
The ratio of the least to highest stress is known as the stress ratio. 345 mpa is the greatest stress level.
Explain about the maximum stress level?
The mean stress is 60 mpa. The highest tensile stress and the minimum compressive stress, respectively, are denoted by the words "maximum stress" and "minimum stress." The stress range was established using the absolute difference between the highest and lowest stress.
Maximum stress level = 1/2 of the maximum and minimum stresses.
Then,
60 = 1/2 (Maximum stress minus Minimum stress)
230 = Maximum Stress plus Minimum Stress - (1)
As opposed to that,
Amplitude is= half of the maximum and minimum stresses.
120 = 1/2(Max. stress - Min. Stress) (Max. stress - Min. Stress)
460 equals Maximum Stress - Minimum Stress - (2)
Solving equations (1) and (2) yields:
Equation (1) + (2) 230 = Maximum stress + Minimum stress
460 = Maximum stress - Minimum stress

technician a says that rotors should be measured for thickness variation (parallelism). technician b says that rotors should be measured for lateral runout. who is correct?
Brake rotor micrometer. Parallelism is when the thickness of the rotor varies from point to point.
The parallelism of the brake disc allows the piston to move in and out of the caliper body when pressure is applied. The maximum allowable runout of the rotor friction surface is 0.002 inches (0.050 mm) as specified by most manufacturers.
Steering axle brake pad thickness must be a minimum of 3.2 mm (1⁄8 inch) for air disc brakes and a minimum of 1.6 mm (1⁄16 inch) for hydraulic disc, drum and electric brakes . Runout occurs due to eccentricity (processing error) and axial bending. Both cause uneven distribution of mass around the axis of rotation. Both create destructive forces, cause misalignment, and reduce machine life. Both problems can be serious,

Drum Brakes are mostly to be found on the rear of a modern front wheel drive vehicle.
What Is Drum Brake?
Drum brakes have been around since 1900 ,patented until 1902 by Louis Renault.
A drum brake is a brake that , causes friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum.It rotates at the same speed as the wheel. The drum surrounds a set of brake shoes that are coated in materials that generate friction.Types of drum brakes
