The drum brake shown in the figure has a diameter of \( 300 \mathrm{~mm} \) and is activated by a device that applies the same force \( \mathrm{F} \) on each shoe. The shoes are similar and have a face width of \( 35 \mathrm{~mm} \). The coefficient of the friction is assumed \( 0.3 \) and the pressure limitation is \( 1200 \mathrm{kPa} \). Determine: a) Applied force on each shoe b) The total torque applied on the left and right shoes
