Machining Processes and Machine Tools

Machining is represented as the process in which an excessive amount of substance is eliminated from the particular element in the form of pieces. In machining, cutting tools such as rotary tools, lathe, drill press, grinder, chop saw, welders, and many more are applied to get the desired shape. As compared to other manufacturing processes, machining is precise and versatile.

Question

**Physics Problem on Forces and Torques:**

**Problem Statement:**

The diagram to the left depicts a shelf connected to the wall by a fixed (cantilever) support.

- **Components on the Shelf:**
- A stack of books exerts a vertical force of 18 N at point A.
- A goldfish bowl exerts a vertical force of 36 N at point B.
- A vase exerts a vertical force of 4 N at point C.

- **Shelf Specifications:**
- The length of the shelf is 10 inches.

**Parts of the Problem:**

**a. Draw a free body diagram of the system.**

**Explanation of the Diagram:**
- The shelf is shown horizontally with three vertical downward forces representing the weights of the books, goldfish bowl, and vase.
- They are positioned at different points along the shelf.
- Point A: Stack of books at 3 inches from the wall.
- Point B: Goldfish bowl at 6 inches from the wall.
- Point C: Vase at 10 inches from the wall.

**b. What is the sum of all three forces (R)?**

**Solution:**
- The total vertical force \(R\) can be calculated by summing the individual forces.
\[
R = 18 \, \text{N} + 36 \, \text{N} + 4 \, \text{N} = 58 \, \text{N}
\]

**c. What is \(x\) for the line of action of \(R\)?**

**Approach:**
- The line of action of \(R\) (resultant force) can be found using the principle of moments (centroid of distributed forces). This involves calculating the torque about the fixed support and finding the equivalent position \(x\) where \(R\) acts.

**d. If a hanging plant were to be added exerting a vertical force of 2 N at C, what would the new \(x\) be?**

**Additional Information:**
- The new force scenario includes an additional 2 N at point C, making the forces:
- Books: 18 N at A
- Goldfish Bowl: 36 N at B
- Vase: 4 N at C
- Hanging Plant: 2 N at C

- Recalculate the total
