F b G When more than two forces are involved, the geometry is no longer parallelogrammatic, but the same principles apply. R , 2 = 5N and 12N at 90* to each other. Our final assumption is that the resultant of two forces doesn't change when rotated. Forces, being vectors are observed to obey the laws of vector addition, and so the overall (resultant) force due to the application of a number of forces can be found geometrically by drawing vector arrows for each force.For example, see Figure 1. there is another force = {\displaystyle \mathbf {e} _{1}} , ) F 2 a At thick plywood piece of thickness 12 mm having substantial metal stand with 2 set of z-pulley and 3 set of ( 50 x 5 gm) slotted weights.

This blog Focuses on the verification of law of forces and also it has clear description of the “LAW OF PARALLELOGRAM OF FORCES”. It is to be noted that the magnitude of the resultant of two vectors is maximum , when the vectors act in the same direction and is minimum when they act in opposite directions. ⊕ G Force is a vector quantity which has both magnitude & direction. F {\displaystyle \det R=1} 2 The law of parallelogram of forces states that if two vectors acting on a particle at the same time be represented in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point their resultant vector is represented in magnitude and direction by the diagonal of the parallelogram drawn from the same point . + ⊕ Thus Resolution of Forces • A single force can be broken into two separate components. Then these forces can be represented as two sides of a parallelogram. According to parallelogram law of vectors , their resultant vector will be represented by the diagonal of the parallelogram . The law of parallelogram of forces states that the vector representing the force equal to the geometric sum of two forces is given by the diagonal of a parallelogram whose sides are the vectors of the two forces. Force is a vector quantity which has both magnitude & direction. APPARATUS: Model of law of parallelogram of forces, strings, weights, hooks, paper etc. Suppose a particle moves at a uniform rate along a line from A to B (Figure 2) in a given time (say, one second), while in the same time, the line AB moves uniformly from its position at AB to a position at DC, remaining parallel to its original orientation throughout.
