Question 4(a) The uniform bar shown in Figure 4 weighs 428 N. It is supported by a pin at A and a cable that runs around the pulley, D. It is subjected to a uniformly distributed load of 17.7 N/m and 12.5 Nm clockwise moment at E. Beam is in equilibrium position as shown in the Figure. Take a = 0.41 m and b = 2.5 m. Determine the tension in the cable and the reaction force at A, both in Newtons. w N/m 75° A ▼▼ ▼ ▼ 12.5 Nm B E 1 m 0.5 m m b Figure 4 Question 4(b) Find a truss from your neighborhood where you can take a photo safely. It does not have to be taken from the perfect angle and as long as we can see the complete truss that is good enough. One photo would be ideal but upto 3 photos can be used. Include these photos in your solutions for this question and based on these photos draw this 2D truss (exact dimensions are not required) with the supports too. Comment on the possible loads and their locations that may be applied to the truss. Discuss the assumptions that you have to…

All members are of negligible weight and all joints are pin connections. The structure is supported by two hinges at point G and K and one roller at point A. Member OP is subjected to a distributed load and is held by two cables IO and NP. The entire system is in equilibrium.
