A single cylinder, four stroke cycle oil engine is fitted with a rope brake. The diameter of the brake wheel is \(600 \mathrm{~mm}\) and rope diameter is \(26 \mathrm{~mm}\). The dead load on the brake is \(200 \mathrm{~N}\) and the spring balance reads \(30 \mathrm{~N}\). If the engine runs at \(450 \mathrm{rpm}\), what will be the brake power of the engine?
