Question
Answer should be Mf = 192..5 lbs and T=15.8lb

Transcribed Image Text:### Problem Statement:
An **L-shaped bracket** is supported by a frictionless pin at point **A** and a cable between points **B** and **D**.
- Point **A** is the origin.
- Point **C** is at coordinates \((-7, 0)\).
- Point **B** is at coordinates \((-7, -10)\).
- The cable is attached between point **B** and an anchor at point **D**, which is at coordinates \((-2, -14)\).
Units are in feet.
A force **F** acts at point **C** at an angle of \(60^\circ\) from the positive x-axis.
### Required:
1. Determine the magnitude of the moment that the force **F** produces about point **A**.
2. Determine the tension required to hold the bracket in position.
### Explanation of Graphs/Diagrams:
Imagine a coordinate system where:
- Point **A** (origin) is where the L-shaped bracket is pinned.
- Point **C** is directly to the left of point **A** on the horizontal axis at \((-7, 0)\).
- Point **B** is directly below point **C** at \((-7, -10)\).
- The cable stretches from point **B** upwards to the anchor point **D**, which is to the right of **B** at \((-2, -14)\).
