The slider crank mechanism shown in Figure 1 consists of a large disk, a connecting rod and a slider. The disk is connected to the pin joint at its center at point A. The connecting rod is connected to the disk at point B with a pin joint. The slider is moving at a constant velocity of 5 m/s. In this mechanism, classify the type of motion that is experienced by the disk, the connecting rod, and the slider. In the range of 30 s 05 90°, choose three (3) angles to show the instantaneous center changes with the mechanism movement. Then, based on one of the 0 that you have mentioned previously, compute an acceleration vector of point C in terms 216 and an

Figure 13 shows a simple model of a machine part, with an applied moment applied clockwise to the disc. The disc rotates without translation. Assume that the mass is on a frictionless surface and also that the disc rotates around the shaft with no friction effects. (a) Determine the kinetic and potential energy of the system. (b) Determine the equation of motion of the system using Lagrange’s equation.

Torsional springs provide a simple propulsion mechanism for toy cars. When the rear wheels are rotated asif the car were moving backward, they cause a torsional spring (with one end attached to the axle and the other to thebody of the car) to wind up and store energy. Therefore, a simple way to charge the spring is to place the car onto asurface and to pull it backward, making sure that the wheels roll without slipping. Note that the torsional spring canonly be wound by pulling the car backward; that is, the forward motion of the car unwinds the spring.Let the weight of the car (body and wheels) be W = 5 oz, the weight of each of the wheels be Ww= 0.15 oz, and theradius of the wheels be r = 0.25 in., where the wheels roll without slip and can be treated as uniform disks. Neglectingfriction internal to the car and letting the car’s torsional spring be linear with constant kt= 0.0002 ft-lb/rad, determinethe maximum speed achieved by the car if it is released from rest after pulling it…
