>>>Can a pine floor stand up to having a ping pong table weighing 170 pounds

>>>something with that weight would leave indentations on the floor?
>>Hi Bob,

>>I see from your site that a white pine floor has a Janka hardness of 380
>>pounds, ie it deforms 0.222" under about 380/(Pi(0.444/2)^2) = 2500 psi.

>>How would we figure the min wheel diameter for a 170 pound pingpong
>>table, if we don't want to score the floor when we move it around
>>on 4 wheels?
...
>At 32.5 Pounds per wheel you don't have much to worry about if you just
>get rubber wheeled casters which are softer than pine and will deform
>before the wood floor does. For example
