Calculate Mechanical Advantage

You apply a force of 18 N on to the end of a lever to open a paint can lid. The

resistance of the lid is 9 N. Calculate the MA.

You apply a force on a crowbar to open a stuck door. The effort length of the

crowbar is 26 cm long and the resistance length is 4 cm. Find the MA of the crowbar.

A worker uses a board that is 4 m long to pry up a boulder. A small rock is used for

a fulcrum and is placed 0.5 m from the resistance end of the lever. Calculate the MA of the board.
