![]() ![]() Substituting the above values of a, we get, The equation for the acceleration can be written by adding the above equation we get The equation for tension force acting on the string is given as Tension force acting on the string when one mass is pulling vertically and another is under the horizontal pull. Since mass m 2 is more than the mass m 1, mass m 2 is pulling the mass m 1 so that mass m 1 is accelerating in the direction of the tension force and the net force acting on the mass is equal to the tension force as gravity is not affecting the acceleration of the mass m 1and m 2 accelerating in the downward direction. The mass m 1 is attached to the string in the horizontal direction, and mass m 2 is hanging vertically. This gives the equation of tension force acting on the string when the two masses are accelerating in the opposite direction.Ĭase(ii): Let two masses m 1 and m 2 are attached to a string as shown in the figure. ![]() To calculate the tension, substituting the acceleration in equations and we get,Įquating the above two equations, we get, This gives the acceleration of the tension acting on the string. Where m 1g and m 2g is the net force acting on the objects, respectively. On adding the above two equations, we get acceleration as Where m 1 g and m 2 g is the net force acting on the objects, respectively. m 2 is accelerating downward due to gravity, and the m 1 is accelerating upward as m 2 is pulling m 1.įor the object accelerating in a downward direction Since the mass of object 2 is more than object1. The mass of the second object is greater than the first object. How To Calculate tension in a string:Ĭase (i): Let us consider two objects of masses m 1 and m 2, pulled by the same string. In this article, we are going to calculate the tension acting on the string. Tension always acts away from the body along the string. Tension is a contact force that transfers by means of string or cable or, similar objects. Before going to calculate the tension in the string, let us discuss what is meant by tension? ![]()
