I think I have to use the formula

torque=rFsin(x)

But I'm not sure if thats right or how to solve it.

**drwls**, Tuesday, January 26, 2010 at 12:39amYou can forget about the sin(x) here because they want you to assume that the force is applied perpendiculat to the pedal crank (even though this is hard to do for a full rotation of a bike pedal crank). So, just multiply 540 N by 0.18 m
