Question

A machine component is subjected to combine bending and torsion. The stresses element on the surface of the machine component is as follows: (a) Using graphical method, draw the Mohr's

circle with a scale of 1cm to 10MP.. (b) From the graph, determine the principal normal stress (61, 02) and the angle(On) acting on the element. (c) From the graph, determine the principal shear stress (t3, T4), Corresponding normal stress (point C) and the angle (0s) acting on the element. (d) Construct the oriented element of the principal normal stress. (e) Construct the oriented element of the principal shear stress. (f) Determine the stresses existing on the plane inclined at 25° clockwise from the vertical. (No need to draw orientated element for this)(2 marks )
