Question

A lever has an input arm that is 2 meters long and anoutput arm that is 3 meters long. What is the mechanicaladvantage? Does this lever multiply force? Why or why not

Answer 1

The formula of the mechanical advantage(MA) of a lever is given as MA = load/effort. Another form of this ma formula is MA = Effort Arm/Load Arm = EA/LA. Example: Calculate the mechanical advantage if 500 N force is needed to overcome the load of 1000 N.
