In physics and engineering, reaction force refers to the force exerted by a surface to support a load. When an object rests on a surface, the surface exerts an equal and opposite force to keep the object in equilibrium. This force is commonly known as the reaction force.
The Formula
The formula for calculating the reaction force can be expressed as follows:
Reaction Force (N) = Force (N) * cos(θ)
Where:
Reaction Forceis the force exerted by the surface (in newtons, N).Forceis the applied force on the surface (in newtons, N).θ(theta) is the angle between the force and the surface (in degrees).
How to Use the Calculator
To calculate the reaction force using the Reaction Force Calculator, follow these steps:
- Input the magnitude of the applied force in newtons (N) in the “Force” field.
- Input the angle (in degrees) between the force and the surface in the “Angle” field.
- Click the “Calculate” button.
- The calculator will compute the reaction force and display the result in newtons (N) in the “Reaction Force” field.
Example
Let’s say you have an object with a force of 100 N applied at an angle of 30 degrees to the horizontal surface. Using the Reaction Force Calculator, you can find the reaction force:
- Input 100 N in the “Force” field.
- Input 30 in the “Angle” field.
- Click “Calculate.”
The calculator will provide the reaction force, which is approximately 86.60 N.
Conclusion
The Reaction Force Calculator is a valuable tool for engineers, physicists, and anyone dealing with objects in equilibrium. It simplifies the calculation of reaction forces and ensures accuracy in various applications.
