Question

Consider a point in a structural member that is subjected to plane stress. Normal and shear stresses acting on horizontal and vertical planes at the point are shown. Determine the principal stresses (sigma_p1 > sigma p_2) and the maximum in-plane shear stress T_max acting at the point. Find the smallest rotation angle theta_p (counterclockwise is positive, clockwise is negative) that will rotate to principal directions. Then show these stresses in an appropriate sketch sigma_p1 = ksi.sigma_p2 = ksi.T_max = ksi.theta_p = 0

Explanation / Answer

sigma1 = 88

sigma 2 = 88

T max = 18+17= 35
