Automobile Engineering MCQs Set6

1. In a differential with a gear ratio of 4 : 1 the drive pinion would revolve four times to cause the ring gear to rotate
2. More often, the condition that draws attention to trouble in the differential is
3. To correct heavy toe contact on ring gear teeth, move the
4. On a straight road, the ring gear
5. In a passenger car a typical arrangement of braking with drum brakes will be
6. Brake efficiency is a term which denotes
7. The most widely used brakes are operated
8. As a rule when comparing the front and rear wheel cylinder pistons it will be found that the pistons in the front wheel cylinders are
9. The type of braking system referred to as power brake, makes use of
10. In the vacuum suspended system, the brakes are applied when
11. In the atmospheric suspended system the brakes are applied when
12. In a vacuum suspended unit, when the brakes are on, the piston or diaphragm has on both sides of it
13. The function of the relay valve in a compressed air brake system is to
14. In the hydraulic braking system, the piston in the master cylinder is connected by mechanical linkage to the
15. In the hydraulic braking system, the movement of the pistons in the wheel cylinder is transmitted to the brake shoes by
16. Two general types of vacuum assisted power brakes are
17. In the integral type of power brake, the diaphragm acts directly on the hydraulic piston in the
18. In the multiplier type of brake, the diaphragm acts directly on the hydraulic piston in the
19. In the power assisted type of brake the bellows applies force to the master cylinder piston
20. In the air brake, air pressure is supplied by
21. Power brakes in general operate making use of the pressure differential between the vacuum from the intake manifold and
22. In the multiplier power brake system, movement of the brake pedal
23. In the power assisted brake system, movement of the brake pedal
24. The metal used for the brake drum is
25. Bleeding of brakes means
26. In trucks the system of wheel braking employed is
27. In jeeps we use
28. In a vacuum type servo-assisted brake system, vacuum is available in ........ is made use of
29. The approximate ratio of effort applied : effort available from servo system is
30. Due to continuous running on a hot day the temperature of the braking fluid will increase, hence some braking torque is applied on brake shoes, to avoid this a small quantity of fluid will be allowed to escape into the master cylinder through
31. As the load on the vehicle increase it demands
32. In the hydraulic brake system, the movement of a piston in the master cylinder produces hydraulic pressure which causes movement of
33. In the case of brake linings saturants and bonding materials are used to
34. Brake lining area required for shoe brakes for trucks is mainly based on
35. The working fluid normally used in hydraulic brake systems is
36. Movement of the brake pedal forces brake fluid from the master brake cylinder through brake lines and into the
37. During braking the brake shoe is moved outward to press against the
38. In the hydraulic brake system, movement of a piston in the master cylinder produces hydraulic pressure which causes movement of the
39. The radius of a pneumatic tyre is
40. For a through inspection a tyre should be
41. If a tube of large size than required is installed in a tyre then
42. Of the four tyres on a car, the one that wears most is the
43. To equalize tyre wear, it is suggested that tyres be rotated from one wheel to another every
44. The distance between dual tyres of vehicles is to be correctly spaced to
45. When an automobile takes a tum to avoid the skidding and over turning
46. Wheels must be balanced
47. Weight can be attached to wheel rim to correct
48. Toe out on turns
49. Caster is defined as the inclination of
50. The Ackermann steering layout
