Q5: Fig. Q5 is a simplified model of car (Quarter car model). It is assumed that (1) the vehicle is constrained to one degree of freedom in the vertical direction, (2) the spring constant of the tires is infinite, that is, the road roughness is transmitted directly to the suspension system of the vehicle, and (3) the tires do not leave the road surface. Assume a trailer has 1,o00 kg mass fully loaded and 250 kg empty. The spring of...

I need to rescale (4) from the first page to the equation on the second page. 2.[60pts.] A bead of mass m is constrained to slide along a straight rigid horizontal wire. A spring with natural length Lo and spring constant k is attached to the bead and to a support point a distance h from the wire. See Figure 1. Let z(t) denote the position of the bead on the wire at time t. (Note that x is measured...

Use ODE’s 2. A mass of 3 slugs (this is the English unit of mass, a pound is a force) is attached to a vertical spring with a spring constant of k = 95. The spring has a dampening constant of B = 6lb The mass is pulled 1 ft below its equilibrium position and released. Determine the equation of motion for the mass. You may use any method you know to solve this problem. (Hint that y'(0) = 0
