Unformatted text preview: following stress function in relation to this problem: Show that the stresses acting on the boundaries satisfy the conditions except for a distributed direct stress at the free end of the beam which exerts no resultant force or bending moment. Problem 3. A steel rod of diameter d = 50 mm (S y = 260 MPa) supports an axial load P = 50R and vertical load R acting at the end of an 0.8-m long arm. Determine the stresses at point A and draw a schematic of the stress state at point A. Given a factor of safety n = 2, compute the largest permissible value of R using the following criteria: (a) maximum shearing stress and (b) maximum energy of distortion....
