In housing construction, flooring is often supported by "joists", which are timber beams spanning the width of the room and simply supported at each end. Suppose a single joist is carrying the weight of three people (450lb450lb) at its center. If the lumber has an allowable stress of 100lb/sqin100lb/sqin, what is the maximum span (in feet) for a 2 by 6 joist? (In reality dimensional lumber such as 2-by-6's are actually smaller than the nominal dimensions, but ignore that for this problem.)
A steel rectangular block, a = 2.4cm wide and b = 1.2 cm deep, is subjected to an axial tensile load as shown in the figure. Measurements show the block to increase in length by x=7.11×10-5m (initial length=10cm) and to decrease width by 8 z = 0.533×10-5m, when P is 45 kN. Calculate the modulus of elasticity and Poisson's ratio for the material. P
