1.Shaft is in tension; D1 = 3", D2 = 1", r at step is 0.1". Max stress has been calculated at 25,400 psi, but how do I calculate the largest hole I can drill in D2 and maintain stress near the hole at or below 25,400?

2.The homogeneous gate shown consists of one quarter of a circular cylinder and is used to maintain a water depth of 4m. That is, when the water depth exceeds 4m, the gate opens slightly and lets the water flow under it. Determine the weight of the gate per meter of length.
