Question

the compound beam is pin connected at c. determine the reaction at support b. 60 lb 300 lb 467 lb 260 lb 133 lb

Explanation:

Step1: Analyze the right - hand part of the beam (from \(C\) to \(B\))

Take moments about \(C\). The moment equation is \(\sum M_{C}=0\).
The forces acting on the right - hand part are the \(200\) lb load, the reaction \(B_y\) at \(B\), and the \(4000\) lb·ft couple.
