## Is spring constant the same as stiffness?

The spring constant, k, is a measure of the stiffness of the spring. It is different for different springs and materials. The larger the spring constant, the stiffer the spring and the more difficult it is to stretch.

### How is stiffness calculated?

Its stiffness is S = F/δ where F is the load and δ is the extension.

**What is stiffness in spring?**

Spring stiffness is the amount of force required to extend a spring by unit length. This can be written like, F = k x. Here F = force. k =stiffness.

**What causes stiffness?**

Muscle stiffness typically occurs after exercise, hard physical work, or lifting weights. You may also feel stiffness after periods of inactivity, like when you get out of bed in the morning or get out of a chair after sitting for a long time. Sprains and strains are the most common reasons for muscle stiffness.

## What is stiffness of a spring?

Stiffness is the extent to which an object resists deformation in response to an applied force. The complementary concept is flexibility or pliability: the more flexible an object is, the less stiff it is.

### What is equivalent stiffness?

In many cases there are several stiffness paths which introduces the need to calculate the ‘equivalent’ stiffness. This is a single stiffness representing the sum of all individual stiffness’ in the appropriate way, taking into account the series/parallel configuration and possible movement amplifications/reductions.

**What is the difference between series connection and parallel connection?**

A series circuit is a circuit in which two components share a common node and the same current flows through them. However, in a parallel circuit, components share two common nodes. In this article, let us look at more differences between series connection and parallel connection circuits.

**What is a series and parallel spring?**

Series and parallel springs – Wikipedia Series and parallel springs From Wikipedia, the free encyclopedia In mechanics, two or more springs are said to be in series when they are connected end-to-end or point to point, and it is said to be in parallel when they are connected side-by-side; in both cases, so as to act as a single spring:

## What is the total twist of a parallel composite shaft?

When shafts are in parallel then the angle of twist in the composite shaft is θ 1 = θ 2 And the total torque transmitted thru the composite shaft (Parallel) T = T 1 + T 2 From the torsion equation, we can write total twist is θ 1 = θ 2 as follows

### How to calculate the stretching force of a spring in parallel?

– the top spring support mg plus the weight of the bottom spring (which is negligible – Thus F is the stretching force for both springs) F=kx22or 2 2 F x k – The total stretch x=+xx12or 12 FF F kk k and 12 11 1 kk k Springs in Parallel – Consider two springs with force constants k1and k2connected in parallel supporting a load F = mg.
