machine design
please step by step solution
2. A single block brake, as shown in Fig. 25.38, has the drum diameter \( 250 \mathrm{~mm} \). The angle of contact is \( 90^{\circ} \) and the coefficient of friction between the drum and the lining is \( 0.35 \). If the torque transmitted by the brake is \( 70 \mathrm{~N}-\mathrm{m} \), find the force \( P \) required to operate the brake. |Ans. \( 700 \mathrm{~N} \) | All dimensions in \( \mathrm{mm} \).
