Wheel & Axle Mechanical Advantage | Equation & Examples - Video | Study.com

Using the wheel and axle illustrated in We know that in one turn of the wheel-axle system, a length of cord equal to the circumference of the wheel or axle will be wound or unwound. IMA =( Distance moved by F)/( Distance moved by FW)=(2 πR)/(2 πr)=(85  cm)/(6.0  cm)=14.2=14 AMA = Force ratio =(400  N)/(50  N)=8.0 Efficiency =(AMA)/(IMA)=(8.0)/(14.2)=0.56=56 % a 400-N load can be raised by a force of 50  N applied to the rim of the wheel. The radii of the wheel (R) and axle (r) a
