The van seen from the rear is traveling at a speed v around a turn of mean radius r banked inward at an angle θ. The effective coefficient of friction between the tires and the road is μ Determine (a) the proper bank angle for a given v to eliminate any tendency to slip or tip, and (b) the maximum speed v before the van tips or slips for a given . Note that the forces and the acceleration lie in the plane of the figure so that the problem may be treated as one of plane motion even though the velocity is normal to this plane.
Assume you are responsible for determining the maximum load that can be carried by a rectangular barge that is 8 m wide and 18 m long. The water line when the barge is empty is 3 m below the level of the cargo deck.
A 75-lb block is supported by the spring arrangement shown. The block is moved vertically downward from its equilibrium position and released. Knowing that the amplitude of the resulting motion is 2 in.,
A 20g mass vibrates accordings to the equation x=0.0009cis(3pit/2 + pi/2). Find the amplitude, period, max velocity, max acceleration, spring constant "K", and the total energy of the system
