machine design

1. A rotating or stationary member, usually of circular cross section much smaller in diameter than its length, used to transmit motion or power; having mounted on it such power-transmitting elements as gears, pulleys, belts, chains, cam, flywheels, cranks, sprockets, and rolling-element bearings.
a) Shaft b) Gear c) Flywheel d) Cam

2. A V-belt transmission system needs:
a) Pulleys b) Sprockets c) Sheaves d) Gears

3. Slip in belt transmission system means:
a) Difference between the angular velocities of two pulleys
b) Difference in the arc of contact between two pulleys
c) Loss of power
d) Difference between the linear speed of the rim of pulley and the belt on it.

4. The equation for the arc of contact of an open belt connection on a bigger pulley.
a) b)
c) d)

5. A shaft intermediate between a line shaft and a driven machine.
a) Counter shaft b) Transmission shaft c) Machine shaft d) Axle

6. A shaft that is used to transmit power between the source and the machine absorbing the power.
a) Line shaft b) Transmission shaft c) Machine shaft d) Counter shaft

7. A shaft forming on integral part of the machine itself is known as:
a) Line shaft b) Machine shaft c) Counter shaft d) Transmission shaft

8. A rotating member that acts as storage reservoir for energy when work is not consumed at as fast a rate as the power is supplied.
a) Shafting b) Cam c) Flywheel d) Storage tank

9. A rigid connector between a shaft and the hub of another component such as pulley, cam, or gear.
a) Key b) Hub c) Bolt d) Pin

10. Which of the following is not true for a key?
a) A demountable machinery part which, when assembled into key-seats, provides a positive means for transmitting torque between the shaft and hub.
b) Prevent relative rotation of a shaft and the member to which it is connected, such as the hub of a gear, pulley, or crank.
c) Prevent relative rotation between the two parts.
d) Connect two
