Question:

Using the wheel and axle illustrated in Fig. 7-3, 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) are 85 cm and 6.0 cm, respectively. Determine the IMA, AMA, and efficiency of the machine. F = 50 N Fw=400 N R Fig. 7-3
