Extracted text: The end of a 2.5 in diameter steel shaft is milled to two flats (one flat on the top and one flat at the bottom) to permit the use of a hand crank. Each flat is located 1.00 in from the center of the shaft. A torque of 750 Ib-in is applied. Find: (a) the maximum shear stress at the end of the shaft with two flats in psi unit. (b) the angle of twist in fadians (c) the angle of twist in degrees h= 1.0 in h= 1.0 in d= 2.50 in Show all your calculations.
