A wrench is used to apply a torque to a bolt. Forces F1 through F6 all have the same magnitude, F, and their directions are per the angle labels in the diagram. For each force, the distance from the point of application to the center of rotation is a multiple of d, as shown. Use the convention that counter-clockwise torques are positive while clockwise torques are negative.
Determine the torque generated by F1 in terms of the variables and angles given in the problem statement. Recall the convention for distinguishing clockwise and counterclockwise torques.
