Which of the following describes a machine that is made up of a lever and a wedge?

simple machine

compound machine

pulley

efficiency

simple machine

Explanation:

A simple machine is any device that changes the magnitude (size) and direction of force. The systems used the system of mechanical advantage to move the system. This is a system that is based on the turning moments principle.

The turning moment is defined buy the equation Ft = Force × distance from the force

The mechanical advantage is the ratio of the work done in overcoming the force to the work done by the force. This cane be given like this:

The mechanical advantage works is in different situations, e.g. lifting a big object with a lever bar.

the answer would be c. motion and direction

i hope this : )
