A store's sign has a mass of 20kg and is 3.0m long. It is uniform, so it's center of gravity is at the center of the sign. It is supported horizontally by a small loose bolt attached to the wall at one end and by a wire at the other end, as shown in the figure. What is magnitude of the net force that the bolt exerts on the sign?

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.
Question
A store's sign has a mass of 20kg and is 3.0m long. It is uniform, so it's center of gravity is at the center of the sign. It is supported horizontally by a small loose bolt attached to the wall at one end and by a wire at the other end, as shown in the figure. What is magnitude of the net force that the bolt exerts on the sign?
Transcribed Image Text:The diagram depicts an inclined plane with an angle of 25 degrees relative to the horizontal. The inclined plane has a length of 3.0 meters measured along the bottom horizontal line from the vertical wall to the point directly beneath the end of the incline.
**Description:**
- The left side of the diagram shows a vertical wall with diagonal lines depicting its texture or material.
- A straight line inclined at an angle of 25 degrees extends from the base of this wall upwards and to the right.
- The angle between the horizontal base and the inclined plane is marked as 25 degrees.
- The distance from the vertical wall to the start of the incline (horizontally) is labeled as 3.0 meters.
This diagram can be used to analyze problems involving inclined planes in physics, such as calculating the components of gravitational force along and perpendicular to the plane, determining the acceleration of objects on the slope, or finding potential and kinetic energy changes as an object moves along the incline.
