A solid 1.25in diameter shaft is used in an aircraft engine to transmit 130HP at 2610 rpm to a propeller that develops thrust of 1540 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 stress is negative. Also, use the naming convention that sp1 is larger algebraically than sp2. Find sp1 in psi Find sp2 in psi Find the magnitude of max shear stress at any point on the outside surface of the shaft.
