Lever: Examples of levers in everyday life include teeter-totters, wheelbarrows, scissors, pliers, bottle openers, mops, brooms, shovels, nutcrackers and sports equipment like baseball bats, golf clubs and hockey sticks. Even your arm can act as a lever.

A pulley:- Pulleys are used in window blinds, on ships to raise and lower sails, elevators, exercise equipment, theater curtains, extension ladders, garage doors and more. Rock climbers also use pulleys to help them climb. As with all simple machines like the pulley, they are designed to help make work easier to do.
eg:-Examples of pulleys include:
- Elevators use multiple pulleys in order to function.
- A cargo lift system that allows for items to be hoisted to higher floors is a pulley system.
- Wells use the pulley system to hoist the bucket out of the well.
- Many types of exercise equipment use pulleys in order to function.
A inclined plane:- Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade.
eg:- Inclined Planes Examples
- Wheelchair ramps.
- Slides.
- Stairs.
- Waterslides.
