Answer 1

Concept:

For a single plate clutch with both sides effective and assuming uniform wear, torque transmitted is:

\( T = 2 \times \mu \times W \times \frac{R_o + R_i}{2} \)

Given:

\( W = 1000~N \), \( R_i = 0.10~m \), \( R_o = 0.15~m \), \( \mu = 0.5 \)

Calculation:

\( T = 2 \times 0.5 \times 1000 \times \frac{0.15 + 0.10}{2} = 1000 \times 0.125 = 125~\text{N·m} \)
