If the effort arm is 1 m and the load arm is 150 cm long, find the MA.

Answer

To find the Mechanical Advantage (MA) given the effort arm and load arm, follow these steps:

### Step-by-Step Solution:

1. **Identify the lengths of the effort arm and load arm:**
- Effort arm = 1 m
- Load arm = 150 cm

2. **Convert the effort arm to centimeters:**
- Since 1 m = 100 cm, the effort arm in centimeters is:
\[ \text{Effort arm} = 1 \, \text{m} = 100 \, \text{cm} \]

3. **Write down the formula for Mechanical Advantage (MA):**
- The formula for Mechanical Advantage is:
\[ MA = \frac{\text{Effort arm}}{\text{Load arm}} \]

4. **Substitute the values into the formula:**
- Substitute the effort arm (100 cm) and load arm (150 cm) into the formula:
\[ MA = \frac{100 \, \text{cm}}{150 \, \text{cm}} \]

5. **Calculate the MA:**
- Perform the division:
\[ MA = \frac{100}{150} = \frac{2}{3} \approx 0.67 \]

6. **State the final answer:**
- The Mechanical Advantage (MA) is approximately 0.67.
