5n∙m of torque to a bolt located at the origin using a wrench that lies along the positive yy-axis. assume the bolt head is at the origin and the threaded portion of the bolt lies along the negative xx-axis. if you apply a 25 n force at the end of the wrench in the direction − what length of wrench would be required to supply the desired torque? under this force are we tightening or loosening the bolt?
