A 40 mm diameter solid brass shaft in a marine vessel is subjectedto a simultaneous torsion of T=250 N.m and axial thrust of P=25kN.
(a) Show the combined state of stress on the surface element of theshaft.
(b) Draw a Mohr's circle for the state of stress shown in part(a).
(c) Determine the magnitude and direction of the principal stressesand show these on a correctly oriented element.
(d) Determine the maximum shearing stress and any coexisting normalstress on the element and show these on a correctly orientedelement.
