Reaction loads at pulley
WebReaction loads: As shown in the free-body diagram, there are three unknown reactions that need to be solved for using the equilibrium condition. Since this represents a two-dimensional force system, we can only make use of three equilibrium equations. We begin the solution by using the equilibrium of moments with point A as the moment center. WebThe forces acting on the pulley due to the object of mass M 2 is F=T-M 2 g M 2 a=T-M 2 g T=M 2 g+M 2 a —- (2) The acceleration of both the masses on the pulley will be at the same rate but only the direction of motion differs. Step 3: Find the acceleration of the objects Now, we have two equations of forces T= M 1 g -M 1 a —- (1)
