1. Which of the following tools is most appropriate for measuring
the flatness of a surface?
a) Micrometer
b) Vernier caliper
c) Dial indicator
d) Torque wrench
Dial indicators are used to measure flatness and deviations from a
reference surface.
2. What is the primary purpose of a key in a shaft-hub assembly?
a) Reduce friction
b) Transmit torque
c) Increase speed
d) Provide lubrication
Keys fit into keyways to lock the shaft and hub together,
transmitting rotational force.
3. Which type of bearing is best suited for handling heavy radial
loads?
a) Thrust bearing
b) Needle bearing
c) Roller bearing
, d) Ball bearing
Roller bearings have line contact, making them better for heavy
radial loads.
4. What is the typical purpose of a lockout/tagout procedure?
a) Increase machine speed
b) Reduce maintenance time
c) Prevent accidental startup during maintenance
d) Improve lubrication
Lockout/tagout ensures machines cannot be energized while being
serviced.
5. When aligning a coupling, which of the following is most critical?
a) Lubrication
b) Surface finish
c) Shaft concentricity and angular alignment
d) Shaft diameter
Proper coupling alignment reduces vibration and prevents
premature bearing and seal failure.
6. What is the main function of a flywheel?
a) Reduce friction
b) Store energy to smooth engine output
c) Act as a counterweight
d) Maintain rotational inertia
Flywheels store rotational energy, helping to smooth the power
delivery of a machine.
7. Which grinding process is primarily used for finishing hardened
steel?
a) Belt grinding
, b) Surface grinding
c) Sanding
d) Lapping
Surface grinding produces precise flat surfaces on hardened steel.
8. What type of maintenance is scheduled based on usage hours or
time intervals?
a) Predictive maintenance
b) Corrective maintenance
c) Preventive maintenance
d) Reactive maintenance
Preventive maintenance is performed at scheduled intervals to
reduce the risk of failure.
9. A V-belt drive transmits power by:
a) Friction only
b) Friction and wedging action
c) Gear teeth engagement
d) Magnetic force
V-belt design allows the belt to wedge into the pulley groove,
increasing torque transmission.
10. What is the function of a keyway in a shaft?
a) Reduce wear
b) Lubrication path
c) Seat the key for torque transmission
d) Adjust shaft length
A keyway is a slot that accommodates a key to transfer rotational
force.
