Chapter 13, Problem 96P

2. The car, having a mass of 1000 kg, is traveling horizontally along a 20° banked track which is circular and has a radius of curvature of p = 100 m. If the coefficient of static friction between the tires and the road is us = 0.3, determine the minimum and maximum constant speed at which the car can travel without sliding down and up the slope. Neglect the size of the car. e= 20°

2. The flatbed railway car travels at the constant speed of 60 km/h around a curve of radius 55 m and bank angle 15°. Determine the smallest static coefficient of friction between the crate and the car that would prevent the crate of mass M from sliding. R = 55 m 15°

Determine the steady-state angle α if the constant force P = 180 N is applied to the cart of mass M = 9 kg. The cart travels on the slope of angle θ = 16°. The pendulum bob has mass m = 3 kg and the rigid bar of length L = 1.2 m has negligible mass. Ignore all friction.
