Name the three major assemblies that make up a disc brake.
The three major assemblies used to make up a disc brake.
Answer to Problem 1SA
The three major assemblies are hub and rotor assembly, a caliper assembly, and the brake pads assembly.
Explanation of Solution
The disc brakes are comprised of three assemblies which are hub and rotor assembly, a caliper assembly, and brake pads assembly. The hub and rotor assembly is divided into two parts i.e. hub and rotor in which hub is the part in which wheel is fitted and may carry wheel bearings also. The rotor is the part which is generally made up with cast iron and is machined in a way that it provides a friction surface for the brake pads.
The caliper assembly is the one which is fitted to convert the hydraulic pressure to the mechanical force and inspects for the lining wear by the hole which is present on top of it. Further, a caliper has a capacity of containing up to six cylinders and pistons that helps in providing same level of pressure distribution.
The brake pad assembly is made up of metal having linings which are either riveted or bonded to them. It helps in straddling the rotor due to its position on each side of calipers. The linings on pads are semi-metallic in nature.
Conclusion:
Thus, the three assemblies which are used in making disc brakes are hub and rotor assembly, a caliper assembly, and the brake pads assembly.

The system is made up of two parallel rectangular steel beams, built-in at one end and simply supported at the other, with closely spaced rollers mounted in-between, for the crate to pass over. a) Using Macaulay notation, carry out an analysis of the problem and calculate the deflection of the mid-length point of the beams when the crate is centrally located, midway between A and B. State any important assumptions used in your analysis.
