Suppose an elastic bar has constant density, , and Young's modulus, E, uniform cross section, and length L. The bar is initially at the rest and lying flat along the interval [0, L]. At the time 0, it is acted on by a force per unit length, acting parallel to the bar at the right end x = L. Use the Laplace transformation to solve this boundary value problem: with B.C.: I.C.: (0,)=0 (, 0) = 0 t>0 x > 0 2 = 2 2 for 0 0 and (,)= and (, 0) = 0 2 2 =
