How are springs that are designed for 100% extension different for ones that are designed for 60% extension?

For a given free length and spring rate there are an infinite number of designs of coil spring. However, there are many practical limitations that limit the options. A spring with a few coils, of thin ...

What are the benefits of using a spring as a drive screw in this electronic deadbolt?

The reason drive screws are used is because they give mechanical advantage. Solenoids are linear devices and don't have inherent use leverage for mechanical advantage. A rotary motor with a small ...

What does squared end spring mean?

Squared means machined to match a flat surface perpendicular to the axis of the spring. The other cheaper option, often found on car suspension, is to just make the mating surface have a surface ...

What happens while skewing a spring?

if the connection at the end of the spring is a pin connection and the deformation is small, not a big change in behavior will happen. we still have $$F=Kx$$ But if the connection is fixed and is not ...

How are springs that are designed for 100% extension different for ones that are designed for 60% extension?

Let's compare two springs of the same alloy but with different numbers of turns $N_1 =2 N_2$ . over the length of the coil, $L$ Now if we extend the coils to a length $$L=2L_{inital}$$ The coils with ...
