Question: "A nut is to be tightened to a torque of 16N m. Calculate the force which must be applied to the end of a spanner of length 24cm in order to produce this torque." This question is so easy, just take the 16 divide by 0.24 and you get the answer. But something is confusing me. Please see attached image. Anyone who would explain it to me, I thank you very much.
