QUESTION 1 XXX = 149 The crane supports a certain load of XXX kg as shown in Figure Q1. (Set XXX as the last three digit in your ID number, (if 0 choose 1) e.g., ID: 123456780, so = 781 kg. Make necessary assumption if needed to solve this problem. (a) For the first case, determine the reactions at the supports A and B as a function of position d of the trolley. Plot a graph of the reactions vs. d, where d: 0.5 m ≤ d ≤3 m. Choose a value for d (b) For the second case, ff the connection at B is changed to a pin type of connection. determine the reactions at the supports A and B as a function of position d of the trolley. Plot a graph of the reactions vs. d, where d: 0.5 m ≤ d ≤3 m. Choose a value for d (c) Compare and suggest the suitable connection to be used in if the smallest average force is needed at both connections A and B. plot graph 5 m XXX = 149 d = choose value anywhere between 0.5 and 3 A Figure Q1
