Equilibrium of forces lab- Sources of error spring scale

  1. Sep 1, 2015 #1
    I'm doing a lab where we use three strings connected to a ring, with each string attached to separate spring scales. What would be sources of error in this? And how does friction affect my results?

    Sounds like you want someone to answer a question on your lab handout... What do you think?
