A highway is designed for traffic moving at 65 mph. There is a portion of the highway that the radius of a curve is 900 ft. The curved is banked shown below so that no friction is required to keep cars on the road. Find, a. The required banking angle θ of the road so that no friction is required. b. The minimum coefficient of friction between the tires and the road that would keep traffic from skidding at this speed if the curve is not banked.

A truck with mass m=1000kg is traveling around a circular curve of radius r=835m when it starts to rain. The coefficient of static friction between the road and the tires is μdry=0.63 when dry, and it is μwet=0.15. The road is level, and the curve is unbanked. (a) When conditions are dry, what is the maximum tangential speed, in meters per second, at which the truck can take the corner at without slipping? 61.74 is wrong. (b) When conditions are wet, what is the maximum tangential speed, in meters per second, without slipping?
15 kg boxes are being transported around a curve via a conveyor belt as shown to the right. Assuming the curve has a radius of 3 meters and the boxes are traveling at a constant speed of 1 meter per second, what is the minimum required coefficient of friction needed to ensure the boxes don’t slip as they travel around the curve?
Calculate the expected acceleration (Eq. 2) and the experimental acceleration (Eq. 3). This hanging mass will supply the unbalanced (net) force acting on the cart. The track is assumed to be frictionless, so the only force present is that from the hanging mass. m1 (hanging mass), m2 (cart).
Small objects are delivered to the 78-in. inclined chute by a conveyor belt A which moves at a speed v1 = 1.7 ft/sec. If the conveyor belt B has a speed v2 = 8.6 ft/sec and the objects are delivered to this belt with no slipping, calculate the coefficient of friction μk between the objects and the chute. angle is 29 deg
In a Porter governor, the mass of the central load is 18 kg and the mass of each ball is 2 kg. The top arms are 250 mm while the bottom arms are each 300 mm long. The friction of the sleeve is 14 N. If the top arms make 45° with the axis of rotation in the equilibrium position, find the range of speed of the governor in that position. 503.2
A skier swoops down a hill and over a ramp as in the diagram below. She starts from rest at a height of 16 m, leaves the 9.0 m ramp at an angle of 45°, and just clears the hedge on her way down, making an angle of 30° with the vertical as she does. Assuming that there is no friction, and that she is small compared to the dimensions of the problem, solve for H, the height of the hedge in metres. Explain what you are doing.

The man is pedaling his bicycle at a constant speed up a slippery slope of 5%. The man and the bicycle have a total mass of 82 kg centered at G. If the rear wheel is about to slip, find the coefficient of friction u between the tire and the road. If the coefficient of friction were doubled, what friction force would act on the rear wheel? (Why can we neglect the friction under the front wheel?)
