Sure! Here’s the Triangle Law of Forces explained in simple and easy language:
What is Triangle Law of Forces?
If two forces are acting on a point, and we draw them as two sides of a triangle (one after the other), then the third side of the triangle (drawn in the opposite direction) shows the total or resultant force.

Q
Steps
A
Steps to Understand:
- Draw the first force F₁ as a line (say from point A to B).
- From the end of that line (point B), draw the second force F₂ (say from B to C).
- Now, draw a line from the start (A) to the end (C). This line AC is the resultant force (R).

R=√f1²+f2²+2f1f2cos theta

Q
