Peel and stick tile has come a long way since the days when it was a cheap and easy if not very attractive way to give old floors new life.
Floor pulls on rough surface.
Fortunately this is not a common occurrence.
Floor buckling happens most often after a floor has been flooded for an extended period of time.
Floor buckling is the most extreme reaction to moisture in a hardwood floor.
The problem is asking us to draw a free body diagram for the box which we already did then to determine the resultant force that acts on the box the acceleration that the box has as a result and the normal force that the surface exerts on the box.
A heavy box is to be dragged along a rough horizontal floor.
This will expose the subfloor underneath which is where most leveling problems lie.
Buckling occurs when the wood flooring actually pulls up from the subfloor lifting several inches in one or more places.
Use a pry bar to pull up hardwood floors one section at a time or unfasten carpet or laminate and roll it up from one end.
You can leave linoleum or sheet vinyl in place if it s difficult to remove or if removal would damage the sub floor.
Some combinations of surfaces such as socks on a wooden floor produce very little friction.
To do so person a pushes it at an angle 30o from the horizontal and requires a minimum force f a while person b pulls the box at an angle 60o from the horizontal and needs minimum force f b.
