Question 1: Analyze the beam shown in fig (a) using the method of least work and determine the reactions at the supports, then draw the shear force and bending moment diagram. Assume the support at A is a pin and B and C are rollers. Take El as constant. 10 k 2.5 k/ft -10 ft+10 ft- 25 ft Fig. a

Please solve all steps properly

The frame shown supports a load W DE 1000 lb through the cable that passes through 3 pulleys and at the end is attached to a frame, also supports the distributed loads ω1 = 100 lb / ft; ω2 = 60 lb / ft and ω3 = 50 lb / ft. Determine: 1. Reactions at supports A and E. 2. Forces acting on bar ABCDE, show the results in graphical form of the beam. That is, you must make the simplified free-body diagram of the loads that act only on the horizontal element. 3. Make the shear force and bending-moment diagrams for the entire beam. The geometry and load data are as follows: see the geometry and load in the images. Clarification: THE CABLE GOES BEHIND THE FRAME AND THE CONTACT IS ONLY WITH THE PULLEYS AND THE GRIP TO THE FRAME (WALL).All pulleys have the same radius.
