A hydraulic brake has master cylinder with area 1.7 cm. The brake cylinder has a cross-sectional area of 6.1 cm. The coefficient of friction between the shoe and wheel drum is 0.4. If the wheel has a radius of 44 cm, determine the magnitude of the frictional torque exerted on the wheel around the axle when the driver applies a force of 45 N on the brake pedal. (Note: generally there is a lever system, as well, to amplify the force of the driver's foot!).

Two machines are coupled by means of a clutch plate with 2 contact surfaces. The plate has an inner diameter of 125 mm and an outer diameter of 200 mm and the coefficient of friction between mating surfaces is 0.35. It is assumed that shafts of both machines are co-axial and the driving shaft is rotating at a constant speed of 240 rev/min when it is suddenly brought in contact with the driven shaft/machine initially rotating at 20 rev/min. The Moment of Inertia of the driven machine is 21 kgm2. A slippage period of 6.8 sec is observed while the driven machine is brought to the full speed of the driving shaft. Analyse the frictional power transmission and calculate: The magnitude of the torque necessary to cause the described acceleration of the driven shaft :
