Question
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. Note: Positive is up (y) and to the
right for x.
