Which lever would be the easiest to lift the load?

...............is example of levers that used to increase force

The force and resistance are equal in levers if ............................

Second class lever, force = 200 Newton. Force arm = 5 cm,

calculate the resistance arm, When the resistance = 100 N.

The type of levers which always saves effort

The length of the force arm of a first class lever is 5 cm. and the

length of resistance arm is 15 cm. if the resistance has a value of 300

Newton, calculate the value of effort force.

The only type of levers, where the arm of force and the arm of resistance are

equal is the.....................
