# What is the force acting on the fixed points of an inclined bar?

• physea
In summary, the conversation discusses a straight bar secured between two walls at an angle to the ground, and the question is about the force applied to the fixed points on the walls. The suggested solution is that the load will be parallel to the weight of the bar at its middle point and the forces will be equal. However, there have been no responses to the question due to negative interactions with the forum's administrators.

## Homework Statement

We have a straight bar of specific length that its edges are secured between two walls. However the bar is not parallel to the ground, but has an angle. My question is, what is the force that pushes each of the two fixed points in the walls, down?

ΣF=0

## The Attempt at a Solution

I think that the load to the fixture points will be parallel to the weight of the bar acting at its middle point. And the forces will be equal. Is that true?

## 1. What is the inclined bar reaction?

The inclined bar reaction is a force that occurs when a bar or beam is placed at an angle, instead of being horizontal. This angle causes a reaction force that is perpendicular to the surface of the inclined bar.

## 2. How is the inclined bar reaction calculated?

The inclined bar reaction can be calculated using trigonometric functions, such as sine and cosine, to determine the force components in the x and y directions. The magnitude of the reaction can then be found using the Pythagorean theorem.

## 3. What factors affect the magnitude of the inclined bar reaction?

The magnitude of the inclined bar reaction depends on several factors, including the angle of inclination, the length of the bar, and the applied force or load on the bar. The material properties of the bar, such as its elasticity and strength, also play a role.

## 4. What is the difference between the inclined bar reaction and the vertical bar reaction?

The inclined bar reaction and the vertical bar reaction are two types of reactions that occur when a bar or beam is loaded. The inclined bar reaction occurs when the bar is at an angle, while the vertical bar reaction occurs when the bar is placed horizontally. The magnitude and direction of these reactions will differ depending on the orientation of the bar.

## 5. How does the inclined bar reaction affect the stability of a structure?

The inclined bar reaction is an important factor in determining the stability of a structure. Inclined bars can provide additional support and help distribute loads more evenly, but they can also create additional forces that must be accounted for in the structural design. The magnitude and direction of the inclined bar reaction must be carefully considered to ensure the overall stability of the structure.
