Which is better for prying open a stuck cover from a can of paint- a screwdriver with a thick handle or one with a long handle? Which is better for turning stubborn screws? Explain
Answer:
A lever works by applying the force as far away from the fulcrum as possible. When using the screwdriver to pry, a thick handle won’t change this distance, but a long handle will. When turning a screw, the fulcrum is along the diameter of the handle, so the wider the handle is, the further the force is from the fulcrum.
