5. Determine the resultant and its distance from point A of the parallel force system acting on beam AB as shown. The forces and positions are given in the figure. Ans. R 115lb downward at 4.66ft to the right of support A. A 20lb/ft 3'. 2016 40lb 3.5'2.5' B

Use "force method" and the table at the back of the exam to determine the reactions (all) of the statically indeterminate 2-span beam shown below. Assume EI is constant for all members. "Must use VB as the redundant reaction force". Mo = 160 ft.-k w = 1.5 k/ft. A B. НА VB Vc 20 ft. 20ft.

subj: civil engineering   A 50-mm diameter bar is used as a simply supported beam 3 m long. The flexural stress is limited to 50 MPa. If w = 36. •Find Fb(bottom) and Ft(top). (F = Mc/I) •Plot the flexural stress and draw a shear & moment diagram.

Q4. An L-shaped beam is being supported by a ball and socket support at O and two cables, AB and CD. A 100 N force is applied downward in the middle of AC. Draw the FBD for solving this rigid body equilibrium question. No need to solve the whole question or write the problem-solving steps. Just draw the FBD.
