A single clutch operating under dry slidingcondition transmits 150 Nm....
- **Given Data**
- Clutch torque: 150 Nm
- Coefficient of friction: 0.3
- Maximum operating pressure: 0.5 MPa
- Ratio of outside radius to inside radius: 1.73
- **Formula**
- $T = \frac{p \times \mu \times R_{\text{mean}}^2}{2}$
- $R_{\text{mean}} = \sqrt{\frac{2T}{p \times \mu}}$
- **Calculations**
- $R_{\text{mean}} = \sqrt{\frac{2 \times 150}{0.5 \times 10^6 \times 0.3}}$
- $R_{\text{mean}} = \sqrt{\frac{300}{0.15 \times 10^6}}$
- $R_{\text{mean}} = \sqrt{0.002}$
- $R_{\text{mean}} = 0.0447$ m
- $R_{\text{inner}} = \frac{R_{\text{mean}}}{1.73}$
- $R_{\text{inner}} = \frac{0.0447}{1.73}$
- $R_{\text{inner}} = 0.0259$ m
- $R_{\text{inner}} = 25.9$ mm
Therefore, the inside radius of the clutch will have to be 25.9 mm for the outside radius to be minimum. The closest option is 54.3 mm (option C).
