The structure AOBCD is suppоrted by а pin аt pоint O аnd a spring at pоint A. It is subjected to a distributed load, a point load and a couple moment, as shown in the figure. When it is held in equilibrium, the stretch of the spring is s = 0.40 m. Determine the force P and the support reactions at the pin to satisfy static equilibrium. Note: To receive full credit for your solution you should show the structure’s FBD and use the coordinate system shown to determine your solution.
