wall bracket, as shown in Fig 2, is subjected to a pull of P =5 kN, at 60° to the
vertical. The cross-section of bracket is rectangular having b=2t. Determine the dimensions b and
t if the stress in the material of the bracket is limited to 28 MPa. Then replace the rectangular
cross-section with hollow circular one to stand the same conditions and calculate the stresses
at points A and B.
