Hello, I have the following problem in geometry: Given a rectangle A, B, C, D consisting of segments AB, BC, CD, DA. At one time I apply vertical displacements at the vertices A, B, C and D perpendicular to the plane of the original rectangle. I have a new quadrilateral A1, B1, C1, D1 in space...

Hello, I'm about elaborating a discrete mass-spring model to describe the vibration of a thin isotropic plate. For the flexion i choose a kind of spiral spring in the two directions X and Y: so the momentums will be Mx= Cbx.(Delta Thêta) ; My = Cby.(Dela Psi). and the energies: Eb =...
