### Concepts Of Forces In Equilibrium

Abstract: The experimentation over here is to find how the upright chemise of an object suspended on a head for the hills surrounded by two pulleys depends on the mountain of the object. To follow through this we naturalised a system and observed the vertical displacement as the central weight varied. The experiment is basically closely the plan of forces in equilibrium. We used the same weights for A and C and they were kept constant throughout the experiment. We changed the weights of B systematically and sight how it make the vertical displacement (height). The results came close enough to our predicted equivalence found on forces and trigonometry. Introduction: The problem was to find the family between free-hanging weights and pulleys, namely the maximum a central mass foundation be without overloading the system. This type of problem is important in a setting where pulleys are in use to discontinue from do contact with a surface. Theory: The apparatus of the experiment is shown by this draw below.
