A laboratory on the concept of static equilibrium uses an apparatus called a force table. The force table consists of a round, level platform marked in degree increments about its circumference. In the center of the table sits a massless ring, to which three strings are tied. Each string is strung over a separate pulley clamped to the edge of the platform, and then tied to a freely-hanging mass, so that each string is under tension and the ring is suspended parallel to the table surface. A mass of ?1=0.145 kgm1=0.145 kg is located at ?1=24.5∘θ1=24.5∘ , and a second mass of ?2=0.227 kgm2=0.227 kg is located at ?2=287∘θ2=287∘ . Calculate the mass ?3m3 and the angular position ?3θ3 (in degrees) that will balance the system and hold the ring stationary over the center of the platform.
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.
