Suppose a spring with a spring constant of 8 N/m is horizontal and has one end attached to a wall and the other end attached to a 4 kg mass. Suppose that the friction of the mass with the floor (i.e., the damping constant) is 3 N·s/m. a. Set up a differential equation that describes this system. Let x to denote the displacement, in meters, of the mass from its equilibrium position, and give your answer in terms of x, x', x''. Assume that positive displacement means the mass is farther from the wall than when the system is at equilibrium. Use g = 9.8 m/sec² as needed. b. Find the general (real-valued) solution to your differential equation from the previous part. Use c1 and c2 to denote arbitrary constants. Use t for independent variable to represent the time elapsed in seconds. Enter c1 as c1 and c2 as c2. Your answer should be an equation of the form x = .... c. Is this system underdamped, overdamped, or critically damped? Enter a value for the damping constant that would make the system critically damped?

A massless physics spring with spring constant K has one end anchored to the ground and the other end connected to a massless string wrapped around a pulley and then connected to a mass on the other side as shown. The string does not slip or slide on the pulley. The pulley is a uniform circular disk with the same mass M as the attached mass. The mass is moved and released, so that the system starts to oscillate. a) Write a Lagrangian that describes the system. b) Use this Lagrangian to write an equation of motion for the hanging mass. c) Find the period of oscillation of the system, in terms of K and M.

2) Calculate the response of the damped spring and mass system under the specified loading conditions. Use the constant average acceleration method and a time increment, Δt, of 0.005 sec. Assume that the system is initially at rest. Calculate the response of the system for damping factors, c, equal to 0.05c_cr, 0.10c_cr, and 0.20c_cr. k = 375 lb/in. m = 0.15 lb-sec^2/in. Plot the displacement histories for each during the time interval between 0 and 0.8 sec. Discuss the influence of the damping factor on the maximum displacement.

00:02 Okay, we have a mass on a spring that has friction.
00:07 So we've given our spring constant, our mass, and our b, which is our damping constant.
00:16 The differential equation looks like this, or written in terms of the numbers like that.
00:22 The solution generally looks like this, where c1 and c2 are arbitrary constants.
00:28 If we substitute into the equation and solve for alpha and omega, which is a long algebraic process, we find that alpha is 3 .8s and omega is a square root of 119 over 8...
