The modulus of elasticity (E) and the moment of inertia (1) are constant for the entire beam. Note: The colors of the loads and moments are used to help indicate the contribution of each force to the deflection or rotation being calculated. The moment diagrams show the moments induced by a load using the same color as the load. • determine the kinematic degrees of freedom The kinematic degrees of freedom are the number of independent joint displacements, in this structure there are two: B A , ~ig\lr~'" I ocations ot kinematic degrees of freedom • determine the fixed end moments due to the applied loads Restrain all degrees of freedom of the structure. From this restrained structure, determine the fixed end forces due to the applied loads (positive moments are in the clockwise...
