Based on some comments You can use the ODE solvers to solve the differential equations directly . For EBT d 2 dx 2 EI d 2 vdx 2 qx . This result is boring if EI is constant and for only point loads applied at the beam end i . e . , in this case vxa 1 a 2 x a 3 x 2 a 4 x 3 . Could be interesting otherwise . Finite element method a method of solving differential equations see Matrix structural analysis by McGuire , Gallagher and Ziemian or many other textbooks . Typically the axial and flexural actions are considered uncoupled effects are negligible for small strains and small displacements . Therefore vx can be found as in 1 . , and u PLEA . <| sep |> Windows Mousekeys are fine . <| sep |> First off remember never play standard or regular hardcore . If you can handle that then try arc , it ' s a very beginner friendly skill . Flameblast is probably the best easy skill to learn and if you want to try a tanky build you can ' t go wrong with earthquake . Do not play melee as anything other than a slayer .
