I have a FBD I'm not quite sure about. I attached what i have along with the original picture. 2 pin supports plus the other one on the hydraulic jack. How does it look? Here's my problem: The chute of a concrete truck for delivering wet concrete to a construction site is shown. The length of the chute may be changed by adding or removing segments BC and CD. Chute segments AB, BC and CD each weigh 50 lb, and the maximum length of the chute is 144 inches. The chute has semicircular shape with 8 inch inside radius, and the hydraulic cylinder GF is used to raise and lower the chute such that. I have to specify the force capacity of the hydraulic cylinder GH. I have to use the max weight on the chute to figure critical weight on the jack. How do I do this without using distributed weight for the chute? I'm not sure of my force arrows at D and H.
