if i have a 100mm x 47mm joist, is there a calculation to work out it's strength? or what weight it can support?
And what if i drill a 10mm hole in the middle of that joist, do i compromise it's strength?
and if i drill two 12.5mm holes above each other, have i reduced the strength of the joist to that of a 50mm joist?
and finally, if i drill one 10mm hole and put a 10mm bolt through, can i expect the strength of the joist to be unaffected?
