Q. A beam of length 4 m. It is supported at 1 m and 3 m from left end of the beam. A udl 2 kN/m is acting on complete length Find the reactions. SOLUTION: Total load = 2 * 4 = 8kN As beam and loading is symmetrical Hence R A =R B = … Read more

Q. A beam 8 m long carries an udl of 2kN / m on the entire span. The beam has an overhang of 1 m and 1.5 m after left hand support and right hand support respectively. The spacing between the supports is 5.5 m. Draw the SFD and BMD indicating the values at salient points.

SOLUTION: Total load= 8 * 2 = 16kN To find the reactions Taking moments about A R{B} * 5.5 + (2 * 1) * 1/2 = (2 * 7) * 7/2 R{B} = (49 – 1)/5.5 = 8.727kN R{A} = 16 – 8.727 = 7.273kN SFD(SHEAR FORCE DIAGRAM) F{D} = F{C} = 0 F{A} (just … Read more
