What is a lever? What is its mechanical advantage?


pls fast I have exam tomorrow​

Answer 1

Answer:

What is a lever ?

A lever is a simple machine comprised of a long beam or rod that is fixed to a pivot point (fulcrum) onto which a load is attached and an effort force is applied. Levers work to reduce the amount of effort force required to move a load, providing a mechanical advantage.

Mechanical advantages :

• The mechanical advantage of a lever is the ratio of the load the lever overcomes and the effort a person or system applies to the lever to overcome some load or resistance.

• The formula of the mechanical advantage(MA) of a lever is given as MA = load/effort.

Answer 2

Answer:

A lever is a simple machine made of a rigid beam and a fulcrum.

The mechanical advantage of a lever is the ratio of the load the lever overcomes and the effort a person or system applies to the lever to overcome some load or resistance. ... The formula of the mechanical advantage(MA) of a lever is given as MA = load/effort.
