4. What is the basic function of the connecting rod?
a) To transmit force from piston to crankshaft
b) To transmit rotary motion from the piston to the crankshaft
c) To transmit oscillation from piston to crankshaft
d) To transmit force from piston to piston pin
Answer: a
Clarification: The major basic function of the connecting rod is to transmit the push and pull forces from the piston to the crankshaft. The force is created by the combustion in the Cylinder.
5. The rod that transmits reciprocating motion to rotary motion is known as?
a) Camshaft
b) Connecting rod
c) Crankshaft
d) Piston
Answer: b
