A filled treasure chest (m = 375 kg) with a long rope tied around its center lies in the middle of a room. Dirk wishes to drag the chest, but there is friction between the chest and the floor with s = 0.52. If the angle between the rope and the floor is 30.0, what is the magnitude of the tension required to just get the chest moving?
Banked curves are designed so that the radial component of the normal force on the car rounding the curve provides the centripetal force required to execute uniform circular motion and safely negotiate the curve. A car rounds a banked curve with banking angle = 22.0 and radius of curvature 150 m. a. If the coefficient of static friction between the cars tires and the road is s = 0.400, what is the range of speeds for which the car can safely negotiate the turn without slipping? b. What is the minimum value of s for which the cars minimum safe speed is zero? Note that friction points up the incline here.

An amusement park ride called the Rotor debuted in 1955 in Germany. Passengers stand in the cylindrical drum of the Rotor as it rotates around its axis. Once the Rotor reaches its operating speed, the floor drops but the riders remain pinned against the wall of the cylinder. Suppose the cylinder makes 24.5 rev/min and has a radius of 3.70 m. What is the minimum coefficient of static friction ?sμs between the wall of the cylinder and the backs of the riders?

A 3500 kg flatbed truck is carrying an unsecured 400 kg box of wine glasses. The coefficient of static friction between the box and the truck bed is Usb=0.50, the coefficient of rolling friction between the truck's tires and the road is Urt=0.03. The truck comes to an unbanked curve in the road having a 40m radius. What is the maximum speed with which the truck can take the curve without damaging the wine glasses? Note that in order for the wine glasses to not be damaged, the box they're in should not slide on the truck bed and the truck itself should not slide on the road while taking the curve.
