Shown is a simple beam with supports at A and B and a force applied at point C. The supports A and B are 1 unit apart for simplicity. The location of the applied force can be moved with the slider. Note how the calculated reaction forces at the supports change with the location of the applied force.[br][br]The play buttons will show the equations used to calculate the reaction forces. There are several methods to calculate the forces and stepping through the equations with the play controls will show different possibilities. Each complete solution shows 4 equations.
