Question #3: (40) A cantilever beam is divided into four triangular elements, as shown in the following figure, and is subjected to a uniform shear force (the resultant is P = 10 kN) at the right end; the elastic modulus E is 200e9 Pa, the Poisson's ratio u is 0.3, and the thickness is 0.1. Show the global stiffness matrix, boundary conditions, the equivalent node force vector and solve the displacement of node 14 2m
