he arm of a crane has a mass of 500 kg and a length of 12 m. It is inclined at an angle of 50 degrees to the horizontal and supports a stationary block of 1200 kg at its end (see diagram). At its base, the arm is fixed to a hinge at point A. A cable C is attached to the arm 8 m from the hinge: it makes an angle of 30 degrees with the arm. The cable C and the rope holding the block have negligible masses. a) Calculate TC, the magnitude of the tension in cable C. b) Calculate the horizontal and vertical components of the force exerted by the hinge on the crane ar
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.
