Answer:
the resultant of forces refers to a single force that can replace multiple forces acting on an object. It is determined by combining the magnitudes and directions of the individual forces. In the given diagram, the resultant force can be found by adding the vector sum of F₁ and F₂ to the force w.
Explanation:
The term "resultant of forces" refers to the single force that can replace multiple forces acting on an object. It is a single force that has the same effect on the object as all the individual forces combined.
To find the resultant of forces, you need to consider both the magnitude and direction of each force. If the forces are acting along the same line, you can simply add or subtract their magnitudes to determine the resultant force.
In the given diagram, there are three forces: F₁, F₂, and w. To find the resultant of these forces, you need to combine their effects. You can do this by adding the forces vectorially.
First, find the vector sum of F₁ and F₂ by adding their magnitudes and considering their directions. Then, add the vector sum of F₁ and F₂ to the force w. The resulting force will be the resultant of the three forces acting on point O.
It's important to note that the resultant force is a single force that can replace the original forces while producing the same effect. This simplifies the analysis of the system and allows us to understand the overall impact of the forces on the object.
To summarize, the resultant of forces refers to a single force that can replace multiple forces acting on an object. It is determined by combining the magnitudes and directions of the individual forces. In the given diagram, the resultant force can be found by adding the vector sum of F₁ and F₂ to the force w.
