very simple question:(adsbygoogle = window.adsbygoogle || []).push({});

Calculate the torque on the pedal shown if a force of 150N was applied in the direction shown.

however, i think im missing the length of the shaft?

since the formula is |T| = |r||F|sin (theta), where's my r value?

is this question unsolveable?
