what are levers? how levers help in reducing effort?
Answers
Explanation:
a rigid bar resting on a pivot, used to move a heavy or firmly fixed load with one end when pressure is applied to the other.
A lever works by reducing the amount of force needed to move an object or lift a load. A lever does this by increasing the distance through which the force acts. ... Instead, they make the work easier by spreading out the effort over a longer distance.
Simply put, levers are machines used to increase force. We call them "simple machines" because they have only two parts — the handle and the fulcrum. The handle or bar of the lever is called the "arm" — it's the part that you push or pull on. The "fulcrum" is the point on which the lever turns or balances.
