Experiment(3): Stiffness Spring (Hooke's Law)

The stiffness factor k for a spring is the same as the deflection coefficient.

In a simple mass-spring system, the relation between force and deflection follows Hooke's Law.

Helical springs are not commonly used in mechanical systems.

The resulting system when a mass is attached to one end of a spring while the other end is fixed is called a simple mass-pulley system.

The natural frequency of oscillation in a simple mass-spring system depends on the mass attached to the spring.

The reciprocal of the stiffness factor k is called the deflection coefficient.

A force-deflection diagram for a helical spring follows a linear relation where force is directly proportional to deflection.

The periodic time of oscillation for a simple mass-spring system can be calculated using $l = 2 ext{π} imes rac{ ext{mass}}{ ext{stiffness}}$

Gravity has no impact on the estimation of the stiffness factor k for a spring.

A ruler is used in the experiment to measure the gravitational acceleration g directly.
