The figure shows a model of a crane that may be mounted on a truck. A rigid uniform horizontal bar of mass my 100.0 kg and length L= 5.700 m is supported by two vertical massless strings. String A is attached at a distance de 1.500 m from the left end of the bar and is connected to the top plate. String B is attached to the left end of the bar and is connected to the floor. An object of mass m₂ = 2000 kg is supported by the crane at a distance 5.500 m from the left end of the bar. Throughout this problem, positive torque is counterclockwise and use 9.807 m/s² for the magnitude of the acceleration due to gravity. Y Part A Find T. the tension in string A. Express your answer in newtons using four significant figures. TA= 7.378x104 N String B String A X mi

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.
