Question

1. the function of this part is to: a. transmit mechanical power by meshing teeth. b. transmit mechanical power by attaching a chain. c. convert mechanical power to gripping force. d. transmit mechanical power by acting as a rigid driveshaft

Explanation:

The image shows cylindrical rods which are likely shafts used in mechanical systems. Shafts are commonly used to transmit mechanical power by attaching a chain (such as in a bicycle chain - drive system). Option A refers to gears meshing, option C is about a different mechanical function related to gripping, and option D is more about a solid, non - flexible driveshaft which these do not seem to represent.

Answer:

B. Transmit mechanical power by attaching a chain.
