The Riemann–Liouvillefractional differential equation (FDE), formulated by R. L. Bagley and P. J. Torvik in 1984, models thevertical motion of a thin plate immersed in a Newtonian fluid, which is held by a spring. From thismodel, we can derive an FDE for the particular case of lacking the spring. Here, we find conditionsfor the source term ensuring that the solutions to the equation of the motion are bounded, which hasa clear physical meaning.
