**Tool Life and Cutting Speed Analysis**

**Question 3:**
Provided below is the tool life data for cutting low carbon steel with a High-Speed Steel (HSS) tool. 

**Tasks:**

1. **Find the n and c exponents for the tool life equation.**

2. **Determine the cutting speed for a 14-minute tool life.**

**Data:**

- **Cutting Speed (ft/min):** 250, 180, 150, 100
- **Tool Life (min):** 2, 5, 10, 30

**Instructions:**

1. **Tool Life Equation:**
   - Use the given data to derive the tool life equation.
   - Plot the data to find the relationship and calculate the exponents.

2. **Calculation:**
   - Use the derived equation to find the cutting speed necessary for a tool life of 14 minutes.

This exercise aims to help in understanding the relationship between cutting speed and tool life, which is crucial for optimizing machining processes.
