Computing Reaction Forces of Supports A & B with a 2 Degree Load

In summary, the reaction forces of Supports A and B can be determined by applying Newton's Second Law and the equations of equilibrium. A 2 degree load refers to a load applied in two directions and is commonly seen in structures experiencing bending or twisting forces. The reaction forces cannot be calculated without knowing the load as it directly affects the equilibrium. The position of the load can greatly impact the reaction forces, with a closer distance resulting in a larger force on that support. Some common methods used to calculate the reaction forces include the method of joints, method of sections, and the graphical method, all utilizing the principles of statics and equilibrium.

Isn't there some theorem that says a distributed load can be considered the same as a concentrated load acting at the centroid? I think some integration is in order.

there are formulas but i forgot them..
 

1. How do you determine the reaction forces of Supports A and B?

The reaction forces of Supports A and B can be determined by applying the principles of Newton's Second Law and the equations of equilibrium. This involves balancing the external forces and moments acting on the structure to solve for the unknown reaction forces.

2. What is a 2 degree load?

A 2 degree load refers to a load that is applied in two directions, such as both vertical and horizontal directions. This type of load is commonly seen in structures that experience bending or twisting forces.

3. Can the reaction forces of Supports A and B be calculated without knowing the load?

No, the reaction forces of Supports A and B cannot be calculated without knowing the load. The load is a crucial factor in determining the reaction forces, as it directly affects the equilibrium of the structure.

4. How does the position of the load affect the reaction forces of Supports A and B?

The position of the load can greatly affect the reaction forces of Supports A and B. If the load is closer to Support A, it will cause a larger reaction force on Support A and a smaller reaction force on Support B. Similarly, if the load is closer to Support B, it will result in a larger reaction force on Support B and a smaller reaction force on Support A.

5. What are some common methods used to calculate the reaction forces of Supports A and B?

Some common methods used to calculate the reaction forces of Supports A and B include the method of joints, method of sections, and the graphical method. These methods utilize the principles of statics and equilibrium to determine the unknown reaction forces.
