As shown in the figure below, a uniform bar with mass m moves freely along a vertical tube at one end, suspended from a spring, and moving along a horizontal tube. At this time, find the equilibrium state, and find the stability of each. (When the spring constant is k and x=0, the spring is not deformed.)

You have a lever, 2m on each side, and four masses: 5kg, 10kg, 15kg and 20kg. You will place the blocks at different positions on the lever such that the two sides balance. Place each block a unique distance from the fulcrum. Use a torque balance to prove the system will not move.

2. Consider a car suspension, modeled as a mass/spring/damper system (mass m, stiffness k, damping b). Suppose the height of the chassis is lo at rest, the height of the terrain below the driver varies as h(t), and the height of the chassis is denoted lo + y(t). (i.e., spring deflection away from rest is y(t) – h(t)). 2 (a) Give the transfer function G(s) = H(s) · = (b) Suppose the ground follows an oscillatory profile h(t) A cos(wx (t)) with magnitude A (in meters) and frequency w (measured in radians per meter). Suppose the car is traveling at a constant forward speed v. Using a frequency response analysis strategy, give the amplitude of oscillations experienced by the driver at steady state as a function of m, k, b, A, w, and v. Hint: You can't simply consider |G(iw)| to get the amplification in this case. (c) Suppose the ground varies by A = 5cm, w = 2 rad/m, and you are driving at v = 15 m/s.

For the single DOF mass-spring system shown in Fig. Q5.a, determine the equivalent springconstant of the system. Assume k1=k2=35 N/m, k3=k4=55 N/m, k5=70 N/m, and k6=20 N/m.
Sketch a free body diagram of your iOlab as you hold in it very steady by the eyebolt attached to the force sensor. What is the net force (the vector sum of forces) on the iOLab? Is the iOLab device accelerating? Explain your answer.
SECTION A Q1. An engine is connected to an unbalanced, rotating shaft as shown in Figure Q1. Viscoelastic shock absorbers are used to mount the engine to a frame. The engine is supported by rigid, frictionless guides that prevent it from moving in the horizontal direction. The shock absorbers can be modelled with a spring-damper system. The spring stiffness of the absorber takes on a value of k = 520 kN/m while its damping coefficient c is unknown. The entire engine-shaft assembly has a mass M of 35 kg. The equivalent mass of the shaft unbalance takes on a value of m = 1.2 kg at an offset distance r = 4 mm rotating at angular velocity w. The unbalanced rotating mass of the shaft results in a force F(t) acting in the vertical direction: F(t) = mw²r sin(wt). The force from the unbalance is causing vibration of the engine within the frame. Whenever the shaft is rotating at its operating speed of 1500 rpm the engine is displaced by a maximum of X = 0.3 mm.
