- A 130-lb crate is being transported by a 175-lb hand- truck cart along the frictionless floor. The coefficients of friction between the cart and the box are μ = 0.20 and Mk = 0.15. If a force P = 45 lb is applied as shown, P determine the smallest ratio d/b for which the box will tip before it slides. Neglect the mass of the wheels of the cart.

The cylinder starts spinning and the riders find that they are “stuck” to the wall and don’t slide down, even if the floor is removed. The ride has a radius of r. The person has a mass of m and is moving with a constant speed of v. The coefficient of static friction between the person and the wall is μs , and kinetic friction μk. The person is only touching the wall, not touching the floor. What is the magnitude of the acceleration of the person? In what direction does it point? The speed is constant. Why is the acceleration not zero? Briefly explain. No equations!arrow_forward
