5. The pedals of a bicycle rotate in a circle with a diameter of 20 cm. What is the maximum torque a 58-kilogram rider can apply by putting all of her weight on one pedal?
Homework Answers
The rider applies a force F = mg when she puts all the weight on the pedal.
Using the formula: torque = r*F, where r is the distance from the
axis. (radius = d/2), we get:
torque = m*g*d/2 = 58*9.8*0.2/2 = 56.84 (N*m).
