Homework Help: Question about torque and friction

  1. Dec 28, 2016 #1
    1. The problem statement, all variables and given/known data
    We have a box has W as widht and h as height.Now when we push it on top of it, it does not slide but the side is closest to us is lifting. We consider center of the mass in center.

    2. Relevant equations

    3. The attempt at a solution
    I think the reason of lifting just one corner is because of friction on the surface and It is not sliding because our torque does not reach maximum value of static friction but I can not write an equation how much force needed to tip it

    Are you asking why the box will tip and not slide? Remember for the box to slide it needs net force and to tip it needs net torque. Try writing the force and torque equations.

    What equations do you know relating to torque?
    Have you drawn a free body diagram?
