Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
The figure (Figure 1) shows a model of a crane that may be mounted on a truck.A rigid uniform horizontal bar of mass m1m1 = 85.0 kgkg and length LL = 5.60 mm is supported by two vertical massless strings. String A is attached at a distance dd = 1.90 mm 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 m2m2 = 2500 kgkg is supported by the crane at a distance xx = 5.40 mm from the left end of the bar.
Throughout this problem, positive torque is counterclockwise and use 9.80 m/s2m/s2 for the magnitude of the acceleration due to gravity.
Find TATA, the tension in string A.
Find TBTB, the magnitude of the tension in string B.
