A mass of 11.1 kg, fastened to the end of an aluminum wire with an unstretched length of 0.54 m , is whirled in a vertical circle with a constant angular speed of 116 rev/min. The cross-sectional area of the wire is 1.5×10−2 cm^2. A. Calculate the elongation of the wire when the mass is at the lowest point of the path. B. Calculate the elongation of the wire when the mass is at the highest point of its path.
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.
