The antitorque wrench is designed for use by a crew member of a spacecraft where no stable platform ex- ists against which to push as a bolt is turned. The pin A fits into an adjacent hole in the space structure which contains the bolt to be turned. Successive os- cillations of the gear and handle unit turn the socket in one direction through the action of a ratchet mechanism. The reaction against the pin A provides the "antitorque" characteristic of the tool. For a gripping force P = 150 N, determine the torque M transmitted to the bolt. (One side of the tool is used for tightening and the other for loosening the bolt.)
