A coach screw is driven into some wood. The screw has a 10mm diameter shank. An axial compressive force of 507N and a torque of 15Nm is applied to the head of the screw. The screw can tolerate a maximum shear stress of 125 MPa. Consider a stress element on the surface of the shank with one side pointing in the axial direction (i.e. dont chose a weird angle). Determine the compressive stress acting on the relevant side of the element (please give an absolute value, MPa) Determine the magnitude of the shear stress acting on the element (absolute value, MPa) Determine the first principal stress acting on the element. (MPa) Determine the factor of safety for the element with respect to shear stress.
