Draw the free-body diagram of the jib crane AB, which is pin-connected at A and supported by member (link) BC. Neglect the weight of the crane. 0.4 m -3 m- 8 kN 4 m BO В Solution 1. Imagine the jib crane A B to be separated or detached from the system. 2. There is a link support at B and the jib crane is (smoothly) pinned at A. Use Table 2.1 (2) and (8) to determine the number and types of reactions acting on the jib crane at A and B. 3. The jib crane is subjected to four external forces. They are caused by: i. iii. ii. iv. 4. Draw the free-body diagram of the (detached) crane showing all these forces labeled with their magnitudes and directions. Assume the sense of the vectors representing the reactions acting on the crane (the correct sense will always emerge from the equilibrium equations for the crane). Include any other relevant information e.g. lengths, angles etc. which may help when formulating the equilibrium equations (including the moment equation) for the jib crane.
