Chapter 5.3, Problem 5.79P
For the beam and loading of Prob. 5.78, determine (a) the distance a for which wA = 20 kN/m, (b) the corresponding value of wB.
In the following problems, use γ = 62.4 lb/ft3 for the specific weight of fresh water and γc = 150 Ib/ft3 for the specific Weight of concrete if U.S. customary units are used. With SI units, use ρ = 103 kg/m3 for the density of fresh water and ρc = 2.40 × 103 kg/m3 for the density of concrete. (See the footnote on page 236 for how to determine the specific weight of a material given its density.)
