# Springs in series (with a little twist)

• lovi
In summary, the concept of "springs in series (with a little twist)" involves connecting multiple springs end-to-end and twisting them together to create a higher stiffness and energy storage capacity compared to individual springs. This is due to the longer effective spring length and the added stiffness from twisting. The arrangement of the springs in series also affects the overall stiffness and energy storage capacity, with parallel arrangements increasing stiffness and series arrangements increasing both. This concept has various real-life applications in industries such as automotive, aerospace, and sports equipment.

I have two springs, they are connected in series.

I have the load-deflection curves for each spring.

How can I get a combined load-deflection curve for the two springs if placed in series?

Thanks

Imagine what happens when they are connected in parallell. Then think the opposite when they are connected in series.

If they are connected in parallel and a load is applied to them, can I assume that the load is distributed equally between the two springs? and that one spring will deflect more than the other?

## What is the concept of "springs in series (with a little twist)"?

The concept of "springs in series (with a little twist)" refers to a situation where multiple springs are connected end-to-end and then twisted together. This results in a combined spring system that has a higher stiffness and can store more energy compared to individual springs.

## How does the stiffness of a combined spring system differ from that of individual springs?

The stiffness of a combined spring system is higher than that of individual springs. This is because the springs are connected end-to-end, resulting in a longer effective spring length, which in turn increases the stiffness of the system. Additionally, the twisting action adds to the overall stiffness of the system.

## What is the effect of twisting on the energy storage capacity of a combined spring system?

The twisting action in "springs in series (with a little twist)" increases the energy storage capacity of the combined spring system. This is because twisting adds to the overall stiffness of the system, allowing it to store and release more energy compared to individual springs.

## How does the arrangement of the springs affect the overall stiffness and energy storage capacity of a combined spring system?

The arrangement of the springs in "springs in series (with a little twist)" can greatly impact the overall stiffness and energy storage capacity of the combined system. When the springs are arranged in a parallel manner, the stiffness of the system increases, but the energy storage capacity remains the same. However, when the springs are arranged in series, both the stiffness and energy storage capacity increase.

## What are some real-life applications of "springs in series (with a little twist)"?

"Springs in series (with a little twist)" have various applications in industries such as automotive, aerospace, and sports equipment. They are commonly used in suspension systems of vehicles to provide a smooth ride, in airplane landing gears to absorb shock, and in tennis rackets to increase the power and control of the player's shots.
