2.16 A two-mass translational mechanical system has the following mathematical model: mi + b₁1+k₁(x1 - x₂) = fa(t) m2 2 + b₂2+k₁(x₂-x₁) + k₂x2 = 0 The displacements x, and x₂ are measured from their respective equilibrium positions. An external force fa(t) is applied to the system. Sketch a possible configuration of the two-mass mechanical system. Label all elements and show the positive convention for displacements on your sketch. Sketch the FBDs for each mass and verify the system model by applying Newton's laws.
2) Consider the spring-mass-damper system hanging down from a ceiling. Initially, the system is at rest. Then, we gently place another mass (M) on top the original one (m). First, please obtain the equation of motion of the mass m in the system (before we placed the other object). Assign the displacement references yourself and obtain the equation accordingly. From the equation of motion, please obtain the transfer function, G(s), between an external force on the mass m , f(t), and the displacement of the mass m, x(t). Then, please obtain the motion of the object M, using the transfer function G(s). Don't forget that G(s) belongs to the system shown on the top! To solve this, represent the force applied by the added mass (M) as a function of time. How would you describe the act of adding a mass as an external force input? Then solve for x(t). c = 10 Ns/m k = 50 N/m m = 5 kg M M = 25 kg F(s) G(s) X(s)

The purpose of the gripper mechanism is to convert input power into the required motion and force to grasp and retain an object. A simple pivot- type gripper is used to hold boxes as shown in Figure Q1. The gripping force (Fg) required to grip the box is 20N at 20 cm from the pivot. The acting force length is 5 cm. Find the actuating force (Fa) by a piston device to close the gripper.
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.
