Mechanical Advantage You can calculate mechanical advantage by comparing the diameters of the two wheels.
Mechanical Advantage MA = LF EF
Calculate MA 38 640 N 2340 N
Compared to levers If this represented the wheels on a car and its axle then the effort force comes from the axle and the load force is on the wheel. We can use the diameter of each wheel as we would use the length of the load arm (load force) and the effort arm (effort force) in a lever. LA EA
Mechanical Advantage MA = dE dL
How mechanical advantage affects distance covered by the wheel
A MA greater than 1 offers a FORCE advantage. • A MA less than 1 offers a SPEED advantage
