2) A machine frame is made of steel having Sy = 400 MPa and Ssy = 250 MPa. When loaded in a test fixture, the stresses were found to vary linearly with load. Two points on the surface were found to be most critical. With a 4-kN test load, stresses at these points were: point a, 0₁ = 200 MPa, 0₂ = 100 MPa; point b, 0₁ = 150 MPa, 0₂ = -100 MPa. Compute the test load at which the frame will experience initial yielding according to the (a) maximum-normal-stress theory, (b) maximum-shear-stress theory, and (c) maximum-distortion-energy theory. Discuss briefly the relative validity of each theory for this application. Considering all the information available, what is your best judgment of the value of the test load at which yielding would actually be expected to begin? 02= 100 MPa a 02 02=-100 MPa b 02 0₁ = 200 MPa 01 = 150 MPa

Three equidistant vertical rods, each of 20 mm diameter, support a load of 25 kN in the same plane as shown in Fig.1 Initially, all the rods are adjusted to share the load equally. Neglecting any chance of buckling, and taking Esteel= 205 GPa and Ecopper 100 GPa, determine the initial and final stresses when a further load of 20 kN is added.
Answer the ff correctly. The rectangular bar shown is connected to a support bracket with a 24 mm diameter pin. The width of the rectangular bar is 70 mm and its thickness is 15 mm. The bearing stress in the bar cannot exceed 120 MPa. Determine the maximum value of Pmax that can be supported based solely on consideration of the bearing stress in the bar. Note: This question is not asking about any stresses in the support bracket...just bearing stress in the rectangular bar.
