F(lb) For protection, the barrel barrier is placed in front of the bridge pier. If the relation between the force and deflection of the barrier is F = (90(10%)x12) lb, where x is in ft, determine the car's maximum penetration in the barrier. The car has a weight of 4000 lb and it is traveling with a speed of 75 ft/s just before it hits the barrier. F = 90(10)*x12 (R)

In a crash test, a car with a mass of 1500 kg is initially moving at a speed of 18 m/s just before it collides with a barrier. The final speed of the car after the collision is zero. The original length of the car is 4.48 m, but after the collision, the smashed car is only 3.86 m long. Making the very rough approximation that the large force that the barrier exerts on the car is approximately constant during...

Overview: The objective of a racetrack impact barrier is to slow a vehicle to a stop with minimal deceleration. It is also critical that the barrier not totally collapse. The figure below shows that the maximum displacement of the barrier wall (before total collapse) is 'd' meters. Kb The motion of the vehicle from the instant it strikes the barrier to the instant it begins "bounce back" is modeled by the following differential equation: Mä(t) + bż(t) +...

Solve and plot with MATLAB . A safety bumper is placed at the end of a racetrack to stop out-of-control cars. The bumper is designed such that the force that the bumper applies to the car is a function of the velocity v and the displacement x of the front edge of the bumper according to the equation: where K = 30 (s kg)/m5 is a constant. A car with a mass m of 1,500 kg hits the bumper at...
