A 240-kip concentric load P is applied to the granite block shown. 6. 6 m. Determine the resulting maximum value of the normal stress. Specify the orientation of the plane on which these maximum values occur. The resulting maximum value of the tensile stress is The resulting maximum value of the compressive stress is |ksi at 8 = ksl at 8= 1.

Determine the principal planes and the principal stresses for the state of plane stress resulting from the superposition of the two states of stress shown. Given: X = 60 MPa and Y = 20 MPa. Determine the orientation of the principal plane in the first and second quadrant. Determine the maximum/minimum principal stresses

The cantilever beam AB will be installed so that the 60-mm side forms an angle β between 0 and 90° with the vertical. The 660-N vertical force P is applied at the center of the free end of the beam. Determine the value of β for which the normal stress at point a is a maximum and the corresponding value of that stress. (Round the final answer to two decimal places.)

1200 N 2. For the bone shown to the left, assume the cross-section at C can be approximated as annular, with an outer diameter of 25mm. When the 1200 N forces are applied, the average normal stress in the bone at point C is determined to be 3.80 MPa. Determine the inner diameter of the bone cross section at C.
