BE CAREFUL EVERYONE HAS GOT THIS WRONG SO FAR!!!!
Question 4 fixed. The shear modulus G and the polar moment of inertia I, of the bar's cross-section are constant along the bar's axis. From the fixed left end (x = 0) of the bar to the middle (x = L/2) of the bar, a lincarly varying distributed torque t, = kr, 0 < x < L/2 is applied (the unit of t, is N-m/m). At the free end (r = L) of the bar, a concentrated torque T is applied (the unit of T is N-m). According to the right-hand rule, the linearly varying distributed torque t, and the concentrated torque T both point to the r-positive direction. Find the angle of twist at the free end (x = L) (Expressing the result with G, Ip, L, T, and k). (Hint: It is easier to find the angle of twist using & = f Figure 1 shows a bar under torsion. The left end of the bar is E.) t, = kx L/2 L/2 Fig. 1. The left end (r = 0) of the bar is fixed, and the right end (r = L) of the bar is applied with a concentrated torque T.
