Question

which of the following systems includes a connecting rod?
a engine mechanical
b supplemental restraint
c suspension and steering
d heating and air conditioning
click the button or type the letter next to your answer.

Explanation:

A connecting rod is a key component in an engine's mechanical system, linking the piston to the crankshaft. Supplemental restraint systems (like airbags) don't use connecting rods. Suspension/steering systems have different components (e.g., control arms, tie rods) but not engine - style connecting rods. Heating and air conditioning systems are for climate control and have no connecting rods. So the engine mechanical system includes a connecting rod.

Answer:

A. engine mechanical
