Question

For each of the plane stress states listed below, draw a Mohr's circle diagram properly labeled, find the principal normal and shear stresses, and determine the angle from the r axis to of. Draw stress elements as in Figure 3-11c and d and label all details.

a.) sigma,x = - 12 kpsi, sigma,y = 22 kpsi, txy = 12 kpsi cw

b.) sigma,x = 30 kpsi, sigma,y = -10 kpsi, txy = 10 kpsi ccw

c.) sigma,x = -10 kpsi, sigma,y = 18 kpsi, txy = 9 kpsi cw

Attached is an image of Figure 3-11c and d for example. THIS IS THE ONLY INFORMATION I AM PROVIDED WITH! Thank you for the help in advance!
