The 35-kg crate is subjected to a force inclined to 700 respect to vertical plane having a constant direction and a magnitude F = 150 N. When s = 20 m, the crate is moving to the right with a speed of 10 m/s. Calculate for normal reaction and its speed when s = 30 m. The coefficient of kinetic friction between the crate and the ground is mk = 0.35.

- Determine the acceleration of the system. - Determine the magnitude of the force that each crate exerts on the other.

The spring-mounted 0.82-kg collar A oscillates along the horizontal rod, which is rotating at the constant angular rate À = 9.1 rad/s. At a certain instant, r is increasing at the rate of 850 mm/s. If the coefficient of kinetic friction between the collar and the rod is 0.56, calculate the friction force F exerted by the rod on the collar at this instant.

A heavy crate with a weight of 160 lbs rests on a floor for which μS = 0.2. Find the minimum force P necessary for impending motion and determine whether the crate slides or tips, given:L1 = 4.4 ft, L2 = 2 ft, θ = 30 °

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°

F 15° 0.6 m 1 m The crate has a mass of 58 kg and rests on the inclined platform of the truck. Determine the minimum acceleration that will cause the crate to tip over or slide relative to the forklift. What is the magnitude of this acceleration? The coefficient of static friction between the packaging and the truck is µs= 0.7.
