The purpose of plotting length of spring vs load is to visualize the relationship between the amount of load applied to a spring and the resulting change in its length. This can help in determining the spring's characteristics, such as its stiffness and maximum load capacity.
The unloaded length of a spring can be found by measuring the length of the spring when it is not under any load. This can be done by placing the spring on a flat surface and measuring from one end to the other using a ruler or caliper.
The extension of a spring refers to the change in its length when a load is applied. It is typically measured in units of length, such as inches or centimeters, and can be calculated by subtracting the unloaded length from the length of the spring under load.
The length of a spring will typically increase as the load applied to it increases. This is due to the spring's elastic properties, which allow it to stretch and store energy when a load is applied. The relationship between length and load can be visualized through a plotting of length vs load.
While a length vs load plot can provide valuable information about a spring's characteristics, it may not always accurately predict the exact length of the spring under a certain load. This is because other factors, such as the material and manufacturing process of the spring, can also affect its length. It is important to use the plot as a guide and conduct physical measurements for accurate results.
