How do you find out stiffness of spring by rectangular footing? - Answers

To determine the stiffness of a spring using a rectangular footing, you can apply a known load to the footing and measure the resulting deflection. The stiffness (k) can be calculated using Hooke's Law, expressed as ( k = \frac{P}{\delta} ), where ( P ) is the applied load and ( \delta ) is the measured deflection. Ensure that the setup is stable and that the load is applied uniformly to obtain accurate results. This method provides an effective way to evaluate the spring's stiffness under realistic conditions.
