A stress element in a rock mass making up a slope experiences a 2D stress as follows: σx = 8 MPa, σy = 4 MPa , tauxy = 3 MPa a. Draw the Mohr circle. On Mohr's circle, mark the location of the x and y planes, mark the angle of rotation θ from the x plane to the σ₁,σ3,and taumax plane. Prove that the angle of rotation of the Mohr circle is 2 times the angle of rotation of the element. b. Write down the coordinates of the center of Mohr's circle and calculate its radius.

The rod is made of A-36 steel and has a diameter of 0.25in. If the rod is 4ft long when the springs are compressed 0.5in and the temperature of the rod is T=40°F, determine the force in the rod when its temperature is T=160°F. k= 1000 lb/in. ww 4 ft k = 1000 lb/in. WW
