Ashaft is subjected to a torque of 28knm and a maximum bending moment of 25knm. the shaft is solid with a diameter of 125mm. i. construct a mohr’s circle on the graph paper provided. ii. using the mohr’s circle method find the values for the principal stresses and the maximum shear stresses on the shaft. iii. show the orientations of the planes on which the principal stresses act on a rotated element. iv. use the complex stress equations to confirm.
