Answer
The correct answer is:
D. Increasing the force on the friction pads and pedaling at the same rate
Work Step by Step
If the force on the friction pads increases, the force of friction would also increase. This would increase the fraction of the cyclist's mechanical power output that is dissipated by the wheel at the friction pads:
The correct answer is:
D. Increasing the force on the friction pads and pedaling at the same rate
