Suppose an automobile engine can produce 195 N⋅m of torque, and assume this car is suspended so that the wheels can turn freely. Each wheel acts like a 14 kg disk that has a 0.195 m radius. The tires act like 2.15-kg rings that have inside radii of 0.18 m and outside radii of 0.34 m. The tread of each tire acts like a 8.5-kg hoop of radius 0.335 m. The 16-kg axle acts like a solid cylinder that has a 1.75-cm radius. The 29.5-kg drive shaft acts like a solid cylinder that has a 3.25-cm radius. Calculate the angular acceleration, in radians per squared second, produced by the motor if 95.0% of this torque is applied to the drive shaft, axle, and rear wheels of a car.

A pair of rods and disc form a triangle with a spring (a spring connects A to C). The spring has a spring constant of 20 N/m and an unstretched length of 1.5m. each rod has a length of 3m and a mass of 10kg. The disk has a mass of 5kg, a radius of .5 and rolls without slipping. The system starts with an angle between the spring and rods of 60 degrees, determine the angular velocity of the rods after it has dropped to a 30 degree angle.

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…
