    I'm stuck on one of the experiment questions based on the princple of moments.
    i) Explain how the upward forces might have been applied and measured in this experiment.
    ii) If the metre stick had not been horizontal how could this arrangement have been used to verify the principle of moments?

    Thank you so much :(
