Let us estimate the value of angle A from angle B. 22 When parallel forces are not in equilibrium, two things are needed to define the resultant force: the magnitude, and the line of action. Answer the following (Use the tail-tip method): a.Draw a diagram showing the forces acting on the object. The effect on a body produced by 2 or more forces acting on it will be the same as that produced by their resultant force. b.Draw a sketch showing the vector sum of two forces. 2. But if they are at an angle then this is the general equation. add the vector equations together to get the vector equation of the resultant force. add the vector equations together to get the vector equation of the resultant force. You can derive this equation from the Pythagorean equation which is only for the the case when the two lines a and b are perpendicular to each other. One force has a magnitude of 10N and the other force has a magnitude of 8N. Step 1: In the given formula, take sin A on left hand side and multiply a with sin B divided by b which gives, sin A = (a x sin B) / b = (5 x sin 30) / 6. If they act on same point, if the angle between forces is theta, then they can be considered as sides of parallelogram. The Question, we a protractor P & Q are two forces ‘ P ’ ‘.
