Question

multiple choice 1 point which of the following best describes the function of a screw? c. splits objects apart a. changes the direction of force b. holds things together or lifts objects d. rotates around a fulcrum

Explanation:

A screw is a simple machine. Its main function is to hold things together (like in fastening) or lift objects (in applications like a jackscrew). Option A: Changing direction of force is more of a lever or pulley. Option C: Splitting objects apart is more of a wedge. Option D: Rotating around a fulcrum is a lever. So the function of a screw is to hold things together or lift objects.

Answer:

B. Holds things together or lifts objects
