The 3600-lb car with rear Wheel drive is attempting to tow the 4500-lb crate. The center of gravity of the car is at G, and the coefficients of static friction are 0.6 at B and 0.2 at C. Determine if the crate will slide.
The 60-lb plank rests on a frictionless roller at A, and the 20-lb triangular support BD. Both bodies are homogenous. The coefficients of static friction are 0.4 at B and 0.3 at D. Determine the largest force P that can be applied to the plank without initiating motion.
The 40-lb spool is suspended from the hanger GA and rests against a vertical wall. The center of gravity of the spool is at G and the weight of the hanger is negligible. The wire wound around the hub of the spool is extracted by pulling its end with the force P. If the coefficient of static friction between the spool and the wall is 0.25, determine the smallest P that will extract the wire.
The brake pads at C and D are pressed against the cylinder by the spring BF. The coefficient of static friction between each pad and the cylinder is 0.15. Find the smallest tension in the spring that would prevent the cylinder from rotating when the clockwise couple M=2200lbin. is applied. Neglect the weights of the members.
Determine the maximum acceleration that can be achieved by the car without having the front wheels A leave the track or the rear drive wheels B slip on the track. The coefficient of static friction is ??= 0.9. The car's mass center is at G, and the front wheels are free to roll. Neglect the mass of all the wheels.
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?)
The box B weighs 50lb. The coefficients of friction between the cable and the fixed round supports are µs=0.40 and µk=0.30. What is the minimum force F required to support the box? What force F is required to move the box upward at a constant rate?

The 136-kg industrial door with mass center at G is being positioned for repair by insertion of the 6° wedge under corner B. Horizontal movement is prevented by the small ledge at corner A. The coefficients of static friction at both the top and bottom wedge surfaces are 0.58. Calculate the rightward force P' which would remove the wedge from under the door. Assume that corner A does not slip for your calculation of P, but then check this assumption; the coefficient of static friction at A is 0.58.
