Question

6. (5 points) The rigid har ABC is suspended from three steel wires as shown Cables AB 200 and have a cross sectional area of wood and an elastic modulus of elasticity E GP Draw the free-body-diagram and write the corresponding equations of equilibrium and the compatibility equation necessary if needed to solve this problem. AFTER WRITING THESE EQUATIONS, YOU DO NOT HAVE TO SOLVE FOR THE UNKNOWNS. B RIGID BAR k 0.8 m 0.25 m 0.25 m 80 KN

Answer 1

The solution of the given problem is given below

compatability equation - The third equation involves a little bil- to common sense. The ged equation should be some kind of relation between the de formation in cires. But it not fired any where , there no Pivot Point But the bar is rigid, the de formations can .be examined as such) displace ment due de formation C * 1 iz z 0.8 1.3 X=0.627 71 GB = 1.84 Sc - 2x SA+Sc 1.855 Sa+S- liss SB -> Pc L 1.85 POL ala A AE AE AE PA+Pc 1.85 Pp.
