Question

4.24 Determine the reactions for the beam shown. The beam has a pinned support at one end and a roller support at the other end. Neglect the weight of the beam.

The problem presented is to determine the reactions for a beam with specific loading conditions. The beam is supported by a pinned support at one end (A) and a roller support at the other end (B). The weight of the beam is neglected. **Diagram Details:** - The beam is horizontally oriented and supported at both ends: - **Support A**: Pinned support. - **Support B**: Roller support. - **Dimensions and Loads:** - The total length of the beam (L) is 20 feet. - A 120 lb downward force is applied 2 feet from support A. - An 800 lb downward force is applied 8 feet from the previously mentioned 120 lb force, totaling 10 feet from support A. - A 400 lb force is applied at a 60° angle from the vertical, located 7 feet from the 800 lb force, totaling 17 feet from support A. - **Length Segments:** - The sections from left (A) to right (B) are: - 2 feet from A to the 120 lb force. - 8 feet from the 120 lb force to the 800 lb force. - 7 feet from the 800 lb force to the 400 lb force. - 3 feet from the 400 lb force to B. **Problem Reference:** - This is referenced as Problem 4.24, typically found in educational material related to structural engineering or mechanical engineering courses focusing on statics and strength of materials.
