An experimental engine weighing 480 lb is mounted on a test stand with spring mounts at A
Question:
An experimental engine weighing 480 lb is mounted on a test stand with spring mounts at A and B, each with a stiffness of 600 lb/in. The radius of gyration of the engine about its mass center G is 4.60 in. With the motor not running, calculate the natural frequency (ƒn)y of vertical vibration and (ƒn)θ of rotation about G. If vertical motion is suppressed and a light rotational imbalance occurs, at what speed N should the engine not be run?

In this experiment, we will discuss Newton\'s second law of motion. In this experiment, we use a bucket that is filled with water and attach it to a rope that passes from the pulley. A person is pulling the rope down to lift the bucket filled with water. The question is how much time does a bucket take to fall on the ground when we leave the rope? A 2.0 kg bucket is attached to a massless string that is wrapped around a 1.0 kg, 4.0 cm diameter cylinder. The cylinder rotates on an axle through the center. The bucket is released from rest 1.0 m above the floor. How long does it take to reach the floor?
