Kinetics of a rigid body

  1. Nov 9, 2009 #1
    1. The problem statement, all variables and given/known data
    The forklift and operator have a combined weight of 50,000 N and center of mass at G. If the forklift is used to lift the 10,000 N concrete pipe, determine the maximum vertical acceleration it can give to the pipe so that it does not tip forward on its front wheels.


    2. Relevant equations
    [tex]\Sigma[/tex]Fy=Ma
    [tex]\Sigma[/tex]M=0


    3. The attempt at a solution
    [tex]\Sigma[/tex]Fy=Ma: -10000-50000+2*Na+2*Nb=(10000/9.81)*1.2

    [tex]\Sigma[/tex]MG=0: -1.2*(2*Na)+1.8*(2*Nb)+1.5*10000+1.5*((10000/9.81)*1.2)=0

    Solve for 2 equations 2 unknowns and get Na=21.17kN and Nb=9.44kN

    Ok so basically I'm doing some review for an exam and was wondering if my steps to my answer seem alright. This seems a bit too easy to be the correct way to get the answer
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution
