I need the solution for 3-25
![### Mechanics of Materials - Educational Resource
#### Figure P3–23:
A structural shape subjected to a force is shown in the figure where a 60 lb force is applied at an angle of 50 degrees. Additionally, an 80 lb force is applied horizontally at the top. The dimensions of the structure, height of 2 ft for both upper and lower parts, are indicated. There is a marked point A, 3 ft from the vertically applied load.
#### Problem 3–24:
**Objective:** Find the moment about point A for the lever shown in:
- (a) Figure P3–24a
- (b) Figure P3–24b
**Figure P3–24a:**
The diagram shows a symmetrical lever with an applied force of 30 N at an angle of 70 degrees on both sides of point A. The distances from the point of force application to point A are 0.1 m and 0.3 m.
**Figure P3–24b:**
Similar to Figure P3-24a, this diagram also depicts forces of 30 N applied at an angle of 70 degrees. The distances from the application points to point A are both 0.2 m.
#### Figure P3–25:
This figure illustrates a bucket pivoting at point A, with forces acting on it as follows:
- A 26 lb force acting vertically downwards at a distance of 12 in from point A
- A 10 lb load acting horizontally at a distance of 8 in from point A
- Another load acting horizontally at 15 in
**Problem 3–25:** Determine the moment about point A for the given system.
### Explanation of Diagrams and Graphs:
**Figure P3–23:** Depicts a composite shape with dimensions and forces applied. The primary goal is to understand the force effects creating a moment about a specific point 'A'.
**Figures P3–24a and P3–24b:** These figures focus on levers with forces applied at certain angles and distances from a pivot point. The task is to determine how these forces create a moment about the pivot point.
**Figure P3–25:** Similar to the previous figures, this one focuses on calculating the moment produced by various forces acting on a pivoting mechanism (bucket).
This educational task measures the comprehension of moments created by applied forces on different structures which is fundamental in mechanics of materials and structural analysis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F42c853c6-6184-4971-92a2-b66c5e1bdcfe%2F8493f619-32b7-473e-9f75-2eaa89616ed1%2F00cuqfka_processed.jpeg&w=3840&q=75)
