An open belt connects two flat pulleys. The pulley diameters are 300 mm and 450 mm and the corresponding angles of lap are 160° and 210°. The smaller pulley runs at 200 r.p.m. The coefficient of friction between the belt and pulley is 0.25. It is found that the belt is on the point of slipping when 3 kW is transmitted. To increase the power transmitted two alternatives are suggested, namely (i) increasing the initial tension by 10%, and (ii) increasing the coefficient of friction by 10% by the application of a suitable dressing to the belt. Which of these two methods would be more effective? Find the percentage increase in power possible in each case.

On a level test track, a car with anti locks brakes and 90% braking efficiency is determined to have a theoretical stopping distance (ignoring aerodynamic resistance) of 408-ft (after the brakes are applied) from 100-mi/h. The car is rear-wheel drive with a 110-inch wheel base, weighs 3200-lb, and has a 50/50 weight distribution (front to back), a center of gravity that is 22-inches above the road surface, an engine that generates 300-ft lb of torque, an overall gear reduction of 8.5 to 1 (in first gear), a wheel radius of 15-inches and a driveline efficiency of 95%. What is the maximum acceleration from rest of this car on this test track? Thank you for helping.
