1. What is the primary function of a mechanical drive system?
A. Generate electricity
B. Transmit power and motion
C. Store thermal energy
D. Control chemical reactions
Answer: B
Rationale: Mechanical drive systems transfer power from a source to a machine
component.
2. Which component is commonly used to reduce rotational speed?
A. Gear reducer
B. Capacitor
C. Solenoid
D. Transformer
Answer: A
Rationale: Gear reducers decrease speed while increasing torque.
3. What does lubrication primarily reduce in mechanical systems?
A. Voltage
B. Friction and wear
,C. Pressure
D. Magnetic fields
Answer: B
Rationale: Lubrication minimizes friction between moving parts.
4. Which bearing type handles both radial and axial loads?
A. Plain bearing
B. Ball bearing
C. Thrust bearing only
D. Sleeve bearing
Answer: B
Rationale: Ball bearings can support both load types.
5. What is the SI unit of force?
A. Watt
