Homework Help for Mechanical Engineering
Mechanical Engineering uses applied math and physics along with materials science to create the mechanical systems around us. One of the broadest fields within engineering, it helped build cars, skyscrapers and prosthetic limbs!
Consider the beam in Figure.5, assume material Yuang’s modulus E Gpa = 210 and 4 2 A m = × 4.0 10 , the inertia I to be constant throughout the beam, A force of 200N and a moment 500N.m are applied to the beam at mid-length. The left end is fixed support and the right end is pin support.
(1) please discretize the beam into two elements with node 1-3;
(2）obtain the global stiffness matrix
(3)obtain the nodal displacement and unknown rotations at middle nodal.
