(14 The wheelbase of a car is 3-3 m, and the centre of mass is 1 2 m in front of the rear axle and 0-75 m above the ground-level. The coefficient of friction between the wheels and the road is 0-45. Find the maximum acceleration which the car can be given on a level road if it has a rear-wheel drive. Find its maximum deceleration if the braking force on all the wheels is the same and no wheel slip occurs. ​

Steam enters a turbine operating at steady state at 800°F and 450 lbf/in^2 and leaves as a saturated vapor at 1.2 lbf/in^2. The turbine develops 12,000 hp, and heat transfer from the turbine to the surroundings occurs at a rate of 2 x 106 Btu/h. Neglect kinetic and potential energy changes from inlet to exit. Determine the exit temperature, in °F, and the volumetric flow rate of the steam at the inlet, in ft3/s.

A bearing uses SAE 30 oil with a viscosity of 0.1 N·s/m2. The bearing is 30 mm in diameter, and the gap between the shaft and the casing is 2.0 mm. The bearing has a length of 3 cm. The shaft turns at ω = 350 rad/s. Assuming that the flow between the shaft and the casing is a Couette flow, find the torque required to turn the bearing.
