Question
![The image depicts a structural frame composed of two members: AD and DBC. These members are connected via an internal pin at point D. The supports include rollers at points A and B, and a pinned external support at point C.
The diagram illustrates several forces and moments:
- An inclined force \( P \) applied at the leftmost end of the frame, angled at 30 degrees.
- A vertical force \( 2P \) acting at point A.
- A clockwise moment \( M \) applied at point B.
- A vertical force \( 3P \) applied at point C.
Key dimensions are labeled along the beam:
- The segment between points A and D is \( 0.5L \), repeated between D and B, B and C, as well as between A and B, B and C, equaling a total length of 3L.
Problem Statement:
The task is to determine the value of the support reaction \( By \) (the vertical reaction at point B). A positive value indicates an upward force, whereas a negative value indicates a downward force.
Given parameters are:
- \( P = 5.7 \, \text{lb} \)
- \( M = 27.9 \, \text{lb} \cdot \text{ft} \)
- \( L = 3.6 \, \text{ft} \)
The answer should be entered with one decimal precision.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa04f71d2-fda0-4c86-94bd-295f224b82d0%2F0f96876f-1508-4171-b225-047c7b2ab733%2F5hfr27l_processed.png&w=3840&q=75)
