1. A circular shaft with a keyway can be approximated by the section shown in Fig. r=b r 0 r = 2acose Figure 1: Circular shaft with a keyway. The keyway is represented by the boundary equation r = b and the shaft is represented by the boundary equation r = 2a cos 0. Show that using a Prandtl stress function of the form b) = K (6² – 7²) (1 - 7²) (1 - 2a cos) will solve the problem of torsion on this shaft and find the constant K (assume an applied torque T). Compute the shear stress components Taz and Tyz. (Hint: start by converting the stress function to Cartesian coordinates).
