Test: Internal Expanding Brake - Question 3

 The centrifugal force acting on the shoe can never be omitted.

Detailed Solution for Test: Internal Expanding Brake - Question 3

Explanation: Centrifugal force on the internal expanding brakes is generally neglected as it is very small.

Test: Internal Expanding Brake - Question 4

These kinds of brakes require little maintenance.

Detailed Solution for Test: Internal Expanding Brake - Question 4

Explanation: Very little maintenance is required as there is less wear.

Test: Internal Expanding Brake - Question 5

 In internally expanding brake, a large actuating force produces a small braking torque and hence this brake isn’t used generally.

Detailed Solution for Test: Internal Expanding Brake - Question 5

Explanation: Small actuating force produce large braking torque.

Test: Internal Expanding Brake - Question 6

 Heat dissipating capacity of internally expanding brakes is a problem.

Detailed Solution for Test: Internal Expanding Brake - Question 6

Explanation: It has relatively poor dissipation of heat.

Test: Internal Expanding Brake - Question 7

Internally expanding brakes never suffer the problem of self-locking.

Detailed Solution for Test: Internal Expanding Brake - Question 7

Explanation: Due to improper design, wear may be caused which might lead to self-locking of brakes.

Test: Internal Expanding Brake - Question 8

Moment of normal force and frictional forces about the pivot axis are 640000N-mm and 250000N-mm respectively. If force acts at a distance of 190mm from the pivoted point, calculate the actuating force.

Detailed Solution for Test: Internal Expanding Brake - Question 8

Explanation: P=M(n)-M(f)/C.

Test: Internal Expanding Brake - Question 9

Preloading is recommended for bearings.

Detailed Solution for Test: Internal Expanding Brake - Question 9

Explanation: Preloading removes the internal clearances.

Test: Internal Expanding Brake - Question 10

Needles bearings have not much load capacity as they are quite small.

Detailed Solution for Test: Internal Expanding Brake - Question 10

Explanation: Needle bearings have quite large loading capacity as compared to their size.
