A uniform cubical crate is 0.575 m on each side and weighs 900 N. It rests on the floor with one edge against a very small, fixed obstruction. At what height above the floor must a horizontal force of 625.0 N be applied to the crate to just tip it?
net torque about the obstruction is
where:
torque
weight box
torque
of the horizontal force
torque weight box
where:
box weight
distance from the obstruction to the line of action of the box
evaluated numerically
torque of the horizontal force
where:
box weight
height of force F
evaluated numerically
negative because the housing rotates clockwise
finally
if
height above the floor must a horizontal force of 625.0 N be applied
