car
t=25/m
a 1200-kilogram car traveling at a constant speed of 9 meters
per second turns at an intersection.
the car follows a horizontal circular
path with a radius of 25 meters to
point p. at point p, the car hits an
area of ice and loses all frictional
force on its tires. which path does
the car follow on the ice?
(1) a
(2) b

(4) d

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
