A solid 1.25 in. diameter shaft is used in an aircraft engine to transmit 140 hp at 2930 rpm to a propeller that develops a thrust of 1700 lb. Determine the magnitudes of the principal stresses and the maximum shear stress at any point on the outside surface of the shaft. Enter the principal stresses at any point on the outside surface of the shaft. Use the sign convention that a tension normal stress is positive and a compression normal...
