Acar starts from rest and accelerates uniformly to a speed of 72 km/hr over a distance of 500 m a further applied to bring the car to rest under unilorm deceleration in 5 seconds. find the distance travoled during braking acceleration raises the speed to 90 km/hr in 10 seconds. the brakes are now a)-50.5m b)-85.5m c)-625m d)- 45.5

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
