Question 29

A mechanic uses a wrench to loosen a tight bolt on a vehicle wheel. A perpendicular force F F\,F is applied at the end of the wrench handle at a distance d d\,d from the pivot (the center of the bolt).

Which of the following changes would allow the mechanic to loosen the bolt with a smaller force FFF?

A

By using a wrench with a longer handle (increasing ddd).

B

By using a wrench with a shorter handle (decreasing ddd).

C

By using a wrench with a thicker handle.

D

By applying the force at an angle of 30∘30^\circ30∘ to the handle instead of perpendicular.
