Question

Read the statements and choose the correct option. Statement A: The purpose of simple machine is to make work easier by allowing for a push or pull to occur over an increased distance, Statement B: A compound/complex machine is two or more simple machine that are working together to make the work easier,

Answer 1

Answer:

both A and B are true

Explanation:

simple machine

any of several devices with few or no moving parts that are used to modify motion and the magnitude of a force in order to perform work. They are the simplest mechanisms known that can use leverage (or mechanical advantage) to

increase force. The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw.

Complex machines are also called compound machines. Two or more simple machines work together to form a complex machine. Compound machines can do more difficult jobs than simple machines alone. Examples of complex machines are bicycle, wheel barrow, crane, car jack, lawn mover etc.
