# 0840 HYDRAULIC MACHINES (TURBINES-WATER). Basic Module

### マニュアルに含まれるガイド付き実習

1. Investigation of the relationship between the mass of the body, the stiffness of the spring and the period/frequency of oscillation for a simple spring mass system with one degree of freedom.
2. Investigation of the relationship between the applied force, the viscosity of the oil and the velocity for various settings of the adjustable oil damper.
3. Observation of how varying the degree of damping affects the response of a second order mechanical system to a step input.
4. Observation of the free vibrations of a system having one degree of freedom.
5. Study of the effect of viscous damping on the free vibrations of a simple spring-mass-damper system.
6. Determination of the damping ratio for a given spring-massdamper system.
