A simplified model of a basketball hoop is shown. During a basket dunk a player hangs from the rim applying a force of 320 lbs including a dynamic load factor. The stand is a square tube with 5 inches outside length and 0.25 inches thickness. The distance from the edge of the rim to the middle of the square tube is 4 ft. Assuming the model is rigid, the normal stress at point A is most closely equal to: A 36 psi 1284 psi 1248 psi 1212 psi

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.
A (160+Reg. No.) kN force is applied as shown at the end of a hot-rolled steel beam. Neglecting the effect of fillets and of stress concentrations, perform calculations in MS excel or MATLAB for the principal stresses in the beam to satisfy a design specification that they be equal to or less than 150 MPa. If the principal stresses are more than the given value, what would you change in the beam so that satisfy the required stresses. 210 mm 13 mm a 1035 mm 110 mm 160kN +Reg No. 0.4m (b) (a) Figure: Hot-rolled cantilever steel beam a) 3D view of the beam b) Cross-section of the beam
