Question: Three rectangular bars are connected to each other by means of pins. The left end is hinged while the right end is completely fixed

Three rectangular bars are connected to each other by means of pins. The left end is hinged while the right end is completely fixed and the whole assembly is loaded as shown in the figure. 1) Draw the free body diagram of the entire assembly (5 points) 2) Calculate the reactions at the two supports (15 points). All relevant free body diagrams must be clearly drawn. 3) Calculate the average normal and shear stresses acting at a horizontal section (indicated in red) midway of the middle bar. You must clearly indicate whether the normal stress is tension or compression (10 points) Hinge Support 1m 3m 2 kN/m 1m 3 cm Pins 4cm 4m 3m 4m Fixed Support
