Figure Q1 The jib crane is pinned at A and supports a chain hoist that can travel along the bottom flange of the a) the force in rod BC b) the minimum diameter of rod BC (to the nearest 5 mm). c) the minimum diameter of pin B (to the nearest 5 mm). The material properties are listed in Table Q2 and use factor of safety of FS-2 (10 marks) beam boist Figure Q2 Table Q2: Material properties (MPa) Shear Strength (MPa) Tensile Component 200 400 Rod BC 250 550 Pin B (SKMMII13) OUESTION I (10 marks) (a) The steel shaft shown in Figure Qi(a) is made from two segments, AC and CD. The cross sections are shown in Figure Ql(b). If i is fised at its ends A and D and subjected to a soeqae of 1000 Nm, determine (4 marks) torque reactions at A and D, i the maximam shear stress in the shaft Modulus of nigidity, G 77 GPa (2 marka) 1000 N.m 250 mm 100 mm 100 mm Figure Q1(a) section y-y section z-a Figure Q1(b) (b) The two circular rod segments as shown in Figure Ql(c), both made of abaminium, are fixed to the rigid walls such that there is a gap of 0.2 mm between them when the temperature is 30°C What is the final temperature required in order to just close the gap? Each rod has a diameter of 70 GPa 23 x 10 FC, and E (4 marks) 30 mm, uni 100 mm- 200 mm Figure Q1(c) Figure Q1 The jib crane is pinned at A and supports a chain hoist that can travel along the bottom flange of the a) the force in rod BC b) the minimum diameter of rod BC (to the nearest 5 mm). c) the minimum diameter of pin B (to the nearest 5 mm).
