4. The stepped circular bar shown below is made from aluminum (E = 70 GPa, v = 0.35). Each segment is 400 mm in length. Prior to applying the loads, the bar has the dimensions shown. The structure is axially loaded as shown. Determine the stress in each segment, the maximum stress and its location, the final in length of the structure, and the final diameters of each segment due to the applied loads. All dimensions shown are in mm. Ø 25 40 15 ↑ Fu 300 kN 600 kN 300 kN

15 kN 2) Two objects are glued on the angled plane as shown in figure. If the ultimate stress for the glued joint are 20 MPa and 10 MPa for tension and shearing stress respectively, find the value of 0 that corresponds to the maximum factor of safety and find the value of this maximum factor of safety. 0.035 m 0.05 m

Determine the maximum axial force that can be applied to the bar shown in Figure 3. The allowable stress is 100 MPa. The dimensions are: Hole diameter 20 mm. Thickness of bar: 6 mm D = 40 mm d%3D20mm Fillet radius, r = 4 mm 40mm 20 mm r 4 mm 20 mm Figure 3 P.

The supporting wheel on a scaffold is held in place on the leg using a 4-mm-diameter pin as shown. (Figure 1) Figure 1 of 1 > Part A If the wheel is subjected to a normal force of P = 3.3 kN, determine the average shear stress developed in the pin. Neglect friction between the inner scaffold puller leg and the tube used on the wheel. Express your answer to three significant figures and include the appropriate units.
