The torque wrench ABC is used to measure the moment or torque applied to a boll when the bolt is located at A and a force is applied to the handle at C. The mechanic reads the torque on the scale at B. If an extension AO of length D is used on the wrench, determine the required scale reading if the desired torque on the bolt at O is to be M.
