Question

The torque required to turn the crank on an ice cream maker is 4.50 nm how much work does it require to turn the crank 300 full turns?

Answer 1

8,480 Joules. You must multiply by the angle in radians through which the target object rotates. 4.5 x 2 x 3.14 = 28.26666666 J for each turn 28.26666666 x 300 = 8480
