The period/frequency of a simple harmonic motion depends on the factors that affect the restoring force and the inertia of the system. For a spring-mass system, these factors are the spring constant and the mass attached to the spring. Answer and Explanation:1 The ...
11.21. As can be seen from Fig. 11.24, the magnetic suspension system can be assumed to be a mechanical system consisting of a spring and damper. The spring constant and damping coefficient can be given as Sign in to download full-size image Fig. 11.24. Simplified feedback loop when x...
A mass of 0.38 kg is attached to a spring and is set into vibration with a period of 0.22 s. What is the spring constant of the spring? A weight of 12N causes a spring to stretch 3 cm. What is the spring constant k of the spring?
A spring has a spring constant of 81 N \cdot m^{-1} What is the force required to: a) Compress the spring by 6 \ cm, b) Expand the spring by 17 \ cm. A 125 N object vibrates with a period of 3.56 s when hanging from a spring. What is the spring constant of the spring?

By the sixth century BC, most polities became engulfed in a complex web of inter-and intra-lineage struggles, in addition to constant conflicts with neighboring powers. The resultant turmoil may be considered the deepest systemic crisis in Chinese history prior to the first half of the twentieth...
