i got the error. It's formula in my excel which uses 0.6m instead of 0.5m. Anyway, thanks

I'm trying to convert lb/f to kn/m. A concrete has weight of 23.54 kiloNewton/cubic meter which is equal to 150 pounds per cubic feet. For a beam with the following dimensions width = 0.3m = 0.84 feet depth = 0.5m = 1.9685 feet for the beam weight per meter in metric, it is...

If raw carbon fiber has strength of say 4000 mpa, how come it is reduced when put in epoxy laminate to become only 950 mpa?

When you get the square root of something, you are getting the sides (say 3 inches) of a 9 square inches area. So when you are getting the square root of pounds. What sides are you getting? Can you give another example where you need to get the square root of pounds or mile?

please also see page 16 of the above for an actual example of it. Why, what is wrong with lbs = in * in * SQRT (lbs / in^2)? Won't LBS result with the in^2 being canceled by in * in?

Please see Equation 5 of page 9 in http://www.pdhonline.org/courses/s153/s153content.pdf

I'm comparing the shear formula for a beam in english and metric. But it seems the formula or result don't match. In English, the formula is Vc=2*b*d*sqrt(Fc) Given b=11.81102 inches d=18.11024 inches fc=4000 psi Vc=2*b*d*sqrt(Fc)=27056 lbs Now converting the units in metric...
