Answer 2

Answer:

• The lever is one of the fundamental simple machines of mechanics, along with the inclined plane, wheel and axle, screw wedge and pulley, according to the University of Houston's Simple Machines Learning Site.

• People use levers in everything from throwing a ball to a seesaw. While the many advantages of levers are well known, the system has several disadvantages as well.
