M1 Progress Test

  1. Mar 26, 2009 #1
    Hi guys!

    I've totally lost the plot with some questions I have for my progress test, please advise on a method for solution :)

    A Uniform rod (AB) has a length of 1.5m and a mass of 8Kg. A particle of mass 'm'Kg is attached to the rod at B. The rod is supported at the point C (balance point).
    Distance A-C = 0.9m and the system is in equilibrium, with the rod (AB) horizontal.

    Show that mass 'm' = 2Kg.

    Rod AB = 1.5m
    A-C (One end of rod to balance point) = 0.9m
    C-B = 0.6m

    I don't know if this is allowed but can someone who's feeling kind and knowledgeable add me on msn or skype?

    Thanks in advance!
