What is the working depth of the gear and the pinion of the bevel gears?

Mechanical Engineering : Theory of Machines - Quiz(MCQ)

2 m, 0.7 m

3 m, 0.4 m

0.7 m, 2 m

0.4 m, 3 m

Correct Answer : Option (A) : 2 m, 0.7 m

Explanation : The working depth of the teeth is usually 2 m which is the same as for standard spur and helical gears, but the bevel pinion is designed with the larger addendum and has 0.7 m working depth. The gear addendum varies according to the gear ratio and is 1 m for a gear ratio of 1.

A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2 L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will

become equal to 2 R

become equal to R/2

become equal to R/4

remain same as before

Correct Answer :

The D-slide valve is also known as

piston slide valve

outside admission valve

inside admission valve

None of the above

Correct Answer : outside admission valve

When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a

governor

flywheel

D-slide valve
