ABCDE 12 pts] - A massless rigid bar ABCDE is in equilibrium a is subject to a 640 N force at B and a 800 Nmm couple at C. It is supported by a ball and socket joint at A, a cable at D, and a journal bearing at E. Use the isolated bar on the right to draw the free-body diagram to solve for the reactions on ABCDE. If any reaction couples are not engaged, cross them out with a note "N.E." y F 490 mm 200 mm 640 N B 480 mm D E A B D 160 mm 240 mm 800 Nmm C E

Consider the frame below consisting of 3 beams with pins at B, C, and D. Beam CDE is 7 meters long, while beam ABC is 10 meters long. A symmetric distributed load acts on CDE starting at 2 meters from C and ending 4 meters from C. A 49 N downward is exerted 6 m from the C. At E both a 70 Nm moment and a 40 N horizontal force is applied. The structure is securely attached to the ground at point A. a. For the distributed force acting on CDE (between 2 and 4 m from C), find an equivalent force. How far from C does it act? b. Solve for the forces acting on CDE at Pins C and D.
