Question

what is spring stiffness meaning

Answer 1

Spring stiffness:

• Spring stiffness is a characteristic that describes the relationship between load and deflection.
• If k is stiffness, P is load, and x is deflection,
• P = kx
• The smaller the deflection at a constant load, the stiffer the spring, k.
• Simple load-deflection devices or machines that measure deflection as a function of load can be used to determine k for springs and other devices such as beams.

Answer 2

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

x =extension.

•This formula is actually Hooke's law.

•Spring stiffness is inversely proportional to its length.

•Stiffness of spring is useful. Spring stiffness is actually the ability of a spring to resist a force.

•It means the stiffer the spring the larger the force will be to compress or extend the spring.
