Problem 3. (25 points) The rigid frame shown below has a fixed support at Point A. Joints C and Dare rigid joints. Vertical Member ABC is 18-ft long and supports a 20-kip horizontal load (acting to the right) at Point B. A 30-kip horizontal load (acting to the left) is applied to rigid joint C. Horizontal member CD is 12-ft long and supports a uniformly distributed load of 10 k/ft (downward). Vertical member DE is 6-ft long and supports a 20-kip horizontal load (acting to the right) at Point E. (a) Compute reactions at A and E. (b) Draw axial force diagrams, shear force diagrams, and moment diagrams for Members ABC, CD, and DE. Clearly state the exact location(s) of any inflection point(s). 10t/ 30k 12.07 lar 20k 19
