Example 0200 – Cantilever beam

E = 210000N/mm2

n = 0.3L = 100mma = 10mmb = 10mmF = 100N

Objective:Compute the maximum deflection and locatepoint of maximum deflection Tasks:How should this be modelled?Compare results with results obtainedfrom beam theory?Topics:Element type, Real constants, modeling,Plot results, output graphics
