- Problem 1: An internal rim-type brake having an inside rim diameter of \( 300 \mathrm{~mm} \) and a dimension \( R=125 \mathrm{~mm} \) is shown. The shoes have a face width of \( 40 \mathrm{~mm} \) and are both actuated by a force of \( 2.2 \mathrm{kN} \). The drum rotates clockwise. The mean coefficient of friction is \( 0.28 \).
