A car has four identical main wheels (with a failure rate of 0.05 each), and a spare wheel (with failure rate of 0.07). Due to degradation, the spare wheel has a failure rate that occurs while the wheel is not in use of 0.003. Find the expected time of failure of the car due to the wheels.

apply the same torque ? to all four wheels. For
simplicity, also assume that the weight is distributed uniformly so
that all the wheels experience the same normal reaction from the
ground, and so the same frictional force.

A 811 kg car has four 13.1 kg wheels. When the car is moving, what fraction of the total kinetic energy of the car is due to rotation of the wheels about their axles? Assume that the wheels have the same rotational inertia as uniform disks of the same mass and size.

A toy car has a 50g body and four solid wheels, each with a mass of 5g and a radius of 7 mm. The car rolls down a horizontal track at 2 m/s, and at the end of the track it runs into a spring. If the car compresses the spring by 1 cm before bouncing back, what is the spring’s spring constant? Answer: 2400 N/m

5. A car engine powers two front wheels, producing one tire revolution for every four crankshaft revolutions. If the car is moving at 72 mph and has 27 inch diameter tires, what video frame rate would show a mark on one tire as stationary? Would the engine pistons appear stationary if recorded at the same frame rate (assuming the engine block is transparent)? Assume engine drives wheel without any slip.

Another system composes of four items and each one of these items has constant failure rate of 0.0008 failures per hour. These items when they work the system will work. However, when any one of the system's items fails, the whole system will come to a complete halt. Calculate the following: 1. The reliability of the system at 2000 hour running time? 2. The system hazard rate? 3. Mean time to failure of the system?
