Beam Reactions and Equilibrium Analysis

The video tutorial explains the analysis of a simply supported beam with a 15kN load applied at point B. The beam is 5m long with supports at points A and C. The instructor demonstrates how to calculate the reactions at the supports by taking moments about points A and C. The calculations show that the reaction at C (Rc) is 9kN and at A (Ra) is 6kN. The video concludes with a check of vertical equilibrium to confirm the accuracy of the results, ensuring that the sum of reactions equals the applied load.
