Unformatted text preview: nd TC = 50 Nm as shown in Figure 2. The inner core of the shaft from A to C consists of a solid steel material [shear modulus, Gs = 80 GPa] with an outside diameter of 40 mm. From A to B the steel core is covered by an aluminum alloy [shear modulus, Ga = 28 GPa] tube with an inside diameter of 40 mm and a wall thickness of 10 mm. The two materials are bonded together so that they act as a unit. (a) Draw the distribution of the internal torque along the length of bar from A to C. (b) Obtain the angles of twist, φ B and φ C at points B and C, respectively. (c) Calculate the maximum shearing stress in each material and identify the location at which they occur. Name: Signature: Student Number: Marks (%) (30) 3. A simply-supported beam ABC with an overhang is subjected to the loads shown in Figure 3a. The cross-section of the beam has a T-shape as shown in Figure 3b with dimensions as follows: b = 220 mm, t = 15 mm, h = 300 mm, and h1 = 275 mm. (a) Draw the shear force and bending moment distribution diagrams for the beam, labeling all critical values including the maximum bend...
