Calculate the force exerted on the handle of a wheelbarrow

  1. Sep 3, 2009 #1
    1. The problem statement, all variables and given/known data

    The total weight of a wheel barrow filled with gravel=240N
    Wheelbarrow held on an 18 degree incline
    Other dimesions are given as in the figure provided.

    2. Relevant equations
    Assuming that the wheelbarrow is at static equilibrium,

    3. The attempt at a solution

    my attempt of part(a) was to have the total moment=0
    where F represents the uplifting force

    Mc=([tex]\overline{CB}[/tex])(F)-(rxFy)(ryFx)

    = [tex]\sqrt{1.01^2+0.8^2}[/tex](0.2*240cos15)+(0.58*240sin18)

    =0
    but I don't know what to do next....

    Try to calculate:
    [tex]\sum x=0[/tex]
    [tex]\sum y=0[/tex]
    [tex]\sum M=0[/tex]
    I sketched some forces on your picture. I would calculate moment around C.
