The bridge construction company Z is facing problems with the mechanism of the crane, which it uses to lift the beams of the bridges. We have been informed that the bars are made of UNSG 10100 HR steel (Sy= 26x10^3psi, E= 30x10^6psi) and it is required that you determine the maximum weight that the system can support in order to identify what the problem is.
The rigid bar AB with a length of 5m, is attached to two vertical rods and ishorizontal before the uniformly varying load of zero intensity at point A and 10kN/mat point B is applied.
