(a) Figure 6 shows a beam of length 8 m, simply supported at each end, and loaded with a point load of 60 kN and a uniformly distributed load of 30 kN/m over 6m of the beam. (i) Calculate the support reactions and check your answers (ii) Sketch the shear force diagram and the bending moment diagram by inspection. Hence determine the maximum bending moment. 60 kN UDL = 30 kN/m 2 m RI R2 8 m

5. Determine the load in member BC of figure below. A4 12 12 100 kN 100 kN

For the Problem-1, determine the critical load if column ends are fixed instead ofpinned

Example 13 The frame structure shown in Fig. is used to support a hoist for transferring loads for storage at points underneath it. It is anticipated that the load on the dolly is 3kN and the beam CB has a mass of 24 kg/m. Assume the dolly has negligible size and can travel the entire length of the beam. Also, assume A is a pin and B is a roller. Determine the maximum vertical support reactions at A and B and the maximum moment in the -1 m-1.5 m- -1.5 m- beam at D. A 3 kN (a)
