3. If only one person is on the swing in the image below, it is comparable to a point load of = 500 N placed at x = 0.5 m on a wooden branch embedded at one end (cantilever). The length of the branch is 1.5 m. It is given that I = 1x 10- m and E = 2x 10 Nm. The boundary conditions are y(0) = 0, y'(0) = 0,y"(0) M and y'"(0) = -2M. Use your notes to model the fourth order differential equation suited to this application. Present you difforential equation with y subject of the equation. Use the Laplace transform to solve this equation in terms of M. Use your solution to determine the value of M at x = 0.5 m where this branch will break (deflection more %3D %3D %3D than thresh y 2 L ). Do not use Matlab as its solution will not be identifiable in the solution entry. 240
