A center-point bending test was performed on a 2 * 4 wood lumber
according to ASTM D198 procedure with a span of 4 ft and the 4 in. side
is positioned vertically. If the maximum load was 240 kips and the corre-
sponding deflection at the mid-span was 2.4 in., calculate the modulus of
rupture and the apparent modulus of elasticity. See Experiment No. 30 for
equations.
