Worksheet on Simple Machine

Worksheet on simple machine contains various types of questions.

The important information will help us to the answer the questions given below.

Machine: A device, which makes a work easier to do.

Work: Doing a job with the help of energy.

Load: The resistance against any effort given by an object.

Lever: A simple machine with a fulcrum, load arm and effort arm.

Effort: The force applied to a machine to work.

Fulcrum: The pivot of a lever.

Effort arm: Portion between the point of effort and the fulcrum of a lever.

Load arm: Portion between the point of load and the fulcrum of a lever.

Inclined plane: A slope to lift a load from a lower place to higher place reducing the effort required for the lifting.

Pulley: A simple machine made up of wheel to lift things up.

Wheel: A device, that can rotate freely around a central hub.
