1. The problem statement, all variables and given/known data Consider a simply supported beam with a block of mass m placed at the midspan and a spring with spring rate k placed between the beam and the ground at the midspan. Find the spring rate required to reduce the static deflection to one half its original value before the spring was added. 2. Relevant equations F=kδ (d^4δ/dx^4)EI=-w 3. The attempt at a solution I understand the general idea of going about the solution but I'm lost on some reasoning behind it. I realize there are two spring constants, one supplied by the beam's elasticity and another for the spring itself. However it is said that the "springs" are in parallel which I do not understand why this is the case as it appears to me that they would be in series? Could someone please explain this to me?
