The basic differential equation of the elastic curve for a uniformly loaded beam (Figure) is given as
Question:
The basic differential equation of the elastic curve for a uniformly loaded beam (Figure) is given as
El d2y/dx2 = wLx/2 – wx2/2
where E = the modulus of elasticity and l = the moment of inertia. Solve for the deflection of the beam using
(a) The finite-difference approach (Δx = 2 ft) and
(b) The shooting method. The following parameter values apply; E = 30,000 ksi, l = 800 in4, w = 1 kip/ft, L = l0 ft. Compare your numerical results to the analytical solution,
