A left hand threaded 14 mm diameter A36 steel bolt is stuck in a metal block. Assume the bolt head is flush with the block surface at A. In order to remove the bolt the 50 Nm torque is applied to the bolt head as shown. The block applies a resisting torque "t" to the stuck threads which is assumed to be uniformly distributed along the 50 mm buried depth. G = 75 GPa a) Explain the difference between right and left hand threaded bolts Determine: b) The magnitude of the uniform resisting torque "t" (including proper units) c) The internal torque as a function of x measured from B (a FBD is required) d) The maximum shear stress in the bolt Ans: 92.8 MPa e) The angle of twist of bolt head A with respect to end B Ans: 0.0044 rad f) The largest torque that can be applied to the bolt head before it twists off (Tyield = 150 MPa) %3D

Two kinds of stress on a rod are tensile stress and compressional stress and the stress is calculated as the change in length over the total length.     True True False
