Question

Determine the magnitude and direction of the principal voltages for the voltage state given by ?...

Determine the magnitude and direction of the principal voltages for the voltage state given by ? = 200, ? = 400, ?xy= -100, ?zz= ?xz= ?yz= 0 ( all in MPa). Sketch Mohr's voltage circles in the ? ? plane and draw in the xy plane the direction of its main voltages, connected to the correct main voltage.
What is the greatest shear stress for this stress state?

A point in body is in a state of plane stress. The applied direct stress on the face, with normal parallel to the X axis, is 65 MPa with an unknown applied shear stress on the same face. NB - Tensile direct stresses are +ve, Compressive direct stresses are -ve. The maximum in plane shear stress is 111 MPa. The direct stress, on the plane corresponding to maximum shear stress, is 28 MPa. You must use a diagram to illustrate...
