The structure in the figure has a rigid beams ABC (length 58-length BC-2 m) that is supported by cables AD and 8, as well as a pin at C. The cables are made of Aluminam (-70 GPx,dy 500 MPa) and have a circular cross-section with diameter I em T.ength 1.5m The rigid beam will have a uniform distributed load with intensity g and the sense show Find the value of q needed to make the rigid beam roste 0.129 ad calculate the safety fear of cables AD and AD against failure from yielding b. The pit at D, which is in double scan also be a critical structural element. If the flowable show stress for the material of the pin is 250 MPa, what is the minimam diseler rid for the pin at D?
