Finding the thrust of the spring.

[Kiely]

Homework Statement

A spring of modulus 80 N and natural length 60 cm compressed to a length of 35 cm. find the thrust produced.

Homework Equations

Is thrust the opposite of tension? Do we use T=-λ/initial length x (final length-initial length) ? Or do we just solve it without adding a negative sign?

The Attempt at a Solution

T=(80/0.6)x(0.35-0.60)

Hi Kiely!

Is thrust the opposite of tension?

Yes, it's just a fancy word for force (or compression).

And why bother with a sign? … you know it'll be positive, so just write:

T=(80/0.6)x(0.60 - 0.35) ​
