### Problem Description A mechanism supports a structural assembly involving a bar ABC and a cable DE. A turnbuckle T on cable DE is used to adjust the position of roller D to keep bar ABC level. - **Bar ABC**: - Supports a uniformly distributed load of 636 lb/ft across its entire length. - Carries a concentrated load of 1,272 lb at its end point C. - **Cable DE**: - Attached to roller D which can move to maintain the level of bar ABC. - Forms an angle of 60° with the horizontal. ### Dimensions - The span between D and E is 10 ft, divided equally into two segments of 5 ft each. ### Tasks Determine the following forces: - Force at pin A, \( F_A \) - Force at pin B, \( F_B \) - Tension in cable DE, \( F_{DE} \) Inputs required are the magnitudes of these forces in pounds (lb). ### Diagram Explanation - A line diagram of the structure is shown with: - A horizontal beam ABC supported at A and B. - A vertical reaction at point B connecting to a slanted cable DE at a 60° angle from the horizontal. - The beam carries a distributed load, indicated by arrows along its length, and a point load at the end C. This problem involves analyzing a statically determinant structure to find the reaction forces and tension caused by these loads.
