Question

question #10 which of the following is not a machine that makes work easier by changing the direction of the force? ax fixed pulley crowbar single moveable pulley

Explanation:

A fixed - pulley changes the direction of the force. A crowbar can be used to change the direction of the force in some lever - like operations. A single moveable pulley mainly reduces the force required rather than changing the direction of the force in the same way as a fixed pulley. An ax is a cutting tool and does not change the direction of the force in the context of simple machines for force - direction change.
