Homework Help: Finding the thrust of the spring.

  1. Oct 17, 2012 #1
    1. The problem statement, all variables and given/known data
    A spring of modulus 80 N and natural length 60 cm compressed to a length of 35 cm. find the thrust produced.

    2. Relevant 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?

    3. The attempt at a solution

    Hi Kiely! :smile:
    Yes, it's just a fancy word for force (or compression).

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

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