so knowledgeable! I tried to manual estimate the bdft/sqm as per drawing. (vertical stiff.) 0.4 m converted to 1.312 ft and is 8 pcs. : [8(2"x2"x1.312')] / 12 = 3.52 bdft (hori. stiff) 0.298 m converted to 0.98 ft and is 16 pcs : [16(2"x2"x1.312')] / 12 = 5.23 bdft 5.23+3.52 = 8.78 bdft perimeter area of plywood per column : 0.56 sqm 8.78 bdft / 0.56 sqm = 15.68 bdft/sqm total bdft: 15.68 bdft/sqm x 2.24 sqm = 35.12 bdft total pcs= (35.12 bdft x 12" ) / 2"x2"x14' = 7.52 pcs or 8 pcs. ---------------------------------------------------------------------------------------------------- so near. where to get 12.71 bdft? and why divide by 2 ang horizontal sa scaffoldings? thanks
anyway triny ko ireverse compute. 12.71 bdft/sq.m x 4.67 bdft/pc = 2.72 pcs/sq.m* 14ft/pc = 38.14ft/sq.m *0.3048m/ft = 11.625m/sq.m 11.625meters of bracing per square meter yung multipler niya
@@RGbyMariyaEleng Umm for conversion po ata yun kasi inches yung 2x3 tapos yung 14 naka feet. By definition, a board foot po is one square foot, one inch thick. So yung isang naka inches dun kinonvert po into ft. BF=(LxWxD)/12 in²•ft BF=(LxWxD)/144 in³
board foot = volume of wood in inches x feet x feet measurements. 2 inches x 2 inches x 14 feet - one of them is in inches which is why we divide by 12 to convert one of the inches to feet.

(hori. stiff) 0.298 m converted to 0.98 ft and is 16 pcs : [16(2"x2"x1.312')] / 12 = 5.23 bdft
5.23+3.52 = 8.78 bdft
perimeter area of plywood per column : 0.56 sqm
8.78 bdft / 0.56 sqm = 15.68 bdft/sqm
total bdft: 15.68 bdft/sqm x 2.24 sqm = 35.12 bdft
total pcs= (35.12 bdft x 12" ) / 2"x2"x14' = 7.52 pcs or 8 pcs.

so near.
where to get 12.71 bdft?
and why divide by 2 ang horizontal sa scaffoldings?
thanks
Sa ibang source, 29.67 ang multiplier ng 2" x 2" na rough lumber. Ano ba ang talagang tama?
Hi!! Am from Solomon islands I love ur presentation dear 👍👍
@18:09 yung bracing po jan sir is yung diagonal scaffolding?
i'm confused of where did 12.71 BF came from, can anyone explain to me?
30 liters katumbas nun. pero di ko alam saan galing. HAHA

12.71?
@19:36, saan po galing sir yung 12 sa 2"x3"14"/12
Ito rin yung tanong ko. Bakit inover sa 12. Saan po nakuha yung 12

BF=(LxWxD)/12 in²•ft
BF=(LxWxD)/144 in³
2" X 2" X 14' how does 14' is divided by 12 we get in inches
board foot = volume of wood in inches x feet x feet measurements. 2 inches x 2 inches x 14 feet - one of them is in inches which is why we divide by 12 to convert one of the inches to feet.
Ohhhhhh
Di naman po siguro nakapatong yung SOG sa Grade beam no. I mean naka flushed lang siya sa top ng GB.
Thank you po
@11:51 sir saa din po galing yung 12.71 BF/sqm
Oo nga san galing yung 12.71 saka 4.67
ung 12.71 multiplier ata nya para makuha yung bf kung m2 lang given, yung 4.67 is (2x2x14/12) so bale eto yung bf per piece
