Question

technician a says that the connecting rod transfers movement between the crankshaft and the piston. technician b says that the connecting rod can be made of cast iron or powdered metal. who is correct?

a. technician a

b. technician b

c. both technician a and technician b

d. neither technician a nor technician b

Explanation:

• For Technician A: The connecting rod's function is to transfer the reciprocating motion of the piston to the rotational motion of the crankshaft (and vice versa), so Technician A's statement about movement transfer between crankshaft and piston is correct.
• For Technician B: Connecting rods are commonly made from materials like forged steel, but cast iron or powdered metal can also be used for certain applications (e.g., in some smaller or less - high - performance engines), so Technician B's statement about possible materials (cast iron or powdered metal) is also correct.

Answer:

c. Both Technician A and Technician B
