Which component transmit the load from piston to crank in engine ?

  • A.Gudgeon Pin
  • B.Connecting Rod
  • C.Crawk
  • D.Piston

Answer: B

The load is transmitted by the connecting rod.

The connecting rod's small end is attached to the piston through the gudgeon pin and its big end to the crank pin. It carries the force of the gas pressure on the piston to the crank, converting the piston's reciprocating motion into the crankshaft's rotation.

The gudgeon pin only joins the piston to the connecting rod, the piston receives the gas force, and the crank ('Crawk' in the paper) is where the load is delivered, not the part that carries it there.
