|
Board Feet (BF)
|
BF = ((bd)/12) * l * #
b = height d = width l = length # = number of pieces |
|
|
Moment (M)
|
M = FD
F = force D = distance |
|
|
Bending Force (Fb)
|
Fb = M/S
M = max moment S = section modulus |
|
|
Stress (F)
|
F = P/A
P = load A = area |
|
|
Strain (L)
|
L = (PLo) / AE
L = change in length P = load Lo = original length A = area E = modulus of elasticity |
|
|
Thermal Elongation (L)
|
L = CTE (T) (Lo)
L = change in length CTE = coefficient of thermal expansion / contraction T = change in temperature Lo = original length |
