Question
Solve for equilibrium. R1, R2
### Problem 5: Solve for Equilibrium The provided diagram is of a beam subjected to various forces and loads. The elements of the diagram can be described as follows: - The beam is resting on two supports, labeled as R1 and R2. - A point load of 3000 lbs is applied on the left side of the beam. - Two uniformly distributed loads are acting on the beam: - \( w_1 = 750 \, \text{lbs/ft} \) spans over a 12-foot section of the beam. - \( w_2 = 100 \, \text{lbs/ft} \) spans a 4-foot section on the right side of the beam. The distances between these forces and support reactions are as follows: - The span between the two supports (R1 to R2) is divided as follows from left to right: 4 feet, 4 feet, 6 feet, and 4 feet. The task is to solve for the equilibrium of the system, i.e., find the reactions at R1 and R2. ### Problem 13: Solve for Member Forces AB, BD, and BC This task requires determining the internal forces in members AB, BD, and BC of a truss or frame. The details of the truss or frame are not given in the provided image. --- The analysis involves using principles of static equilibrium, including the sum of forces and the sum of moments about any point being zero.
