You open a restaurant and hope to entice customers by hanging out a sign (Figure 1). The uniform horizontal beam supporting the sign is 1.60 m long, has a mass of 20.0 kg , and is hinged to the wall. The sign itself is uniform with a mass of 34.0 kg and overall length of 1.20 m . The two wires supporting the sign are each 34.0 cm long, are 90.0 cm apart, and are equally spaced from the middle of the sign. The cable supporting the beam is 2.20 m long. 1. What minimum tension must your cable be able to support without having your sign come crashing down? 2. What minimum vertical force must the hinge be able to support without pulling out of the wall?
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.
