f r = 3 PLs /2 Sw (St2) | (Equation 21-2) |
where, for the purposes of this section only:
Sw = Width of the test specimen measured parallel to the loading cylinder, inches (mm).
fr = Modulus of rupture, psi (MPa).
Ls = Distance between supports, inches (mm).
St = Thickness of the test specimen measured parallel to the direction of load, inches (mm).
P = The applied load at failure, pounds (N).
