Point B is equidistant from point A and point C.
Fy = -3000 N
Fx = 3000 N
M = -4000 Nm
Determine the principal stresses and the maximum shear stress at points A, B, and C. To obtain point B, perform stress transformation and thus obtain the principal stresses. Calculate the maximum stresses at points A, B, and C. Draw the differential elements for each point and draw the corresponding Mohr's circle for each point.
