Answer 1

A Wedge is made by placing two inclined planes back to back.

A Screw is made by wrapping an inclined plane around a cylinder.

Explanation:

• A wedge is an uncomplicated machine that consists of two sloping planes, providing it a thin end and thick end.
• A wedge is used to separate or split apart objects.
• Force is employed to the thick end of the wedge, and in turn, applies force to the object along both of its sloping sides.
• A screw is a simplistic machine that consists of an inclined plane wrapped around a cylinder or cone.
• The absolute mechanical benefit of wedges and screws is invariably higher than 1.
