Answer 1

Answer:

Explanation:

Simple machines are extremely valuable to engineers since they are used to accomplish extraordinary amounts of work with ease. In particular, engineers can design a simple machine which provides a desired mechanical advantage so that work can be done (more) efficiently and effectively. Even the most complex machines designed by engineers today are a combination of one or more of the six known simple machines. The lever, pulley, and wheel-and-axle can be found in many engineered devices, such as a crowbar, crane, and bicycle.
