WebIt is because when you split forces you have to use the Pythagorean theorem, or hypotenuse^2 = side^2 + side^2. In this case, the hypotenuse is 20 N, and the two sides are 10 N and 10sqrt (3). If you square the hypotenuse, you get 20^2, which equals 400 N. 10^2 + (10sqrt (3))^2 = 100 + 300, which equals 400 N, or the hypotenuse squared.

Triangle and Parallelogram - Important Concepts and Tips for JEE
WebApr 7, 2024 · The law of parallelogram of two forces states that if two vectors acting on a particle at the same time are represented in magnitude and direction by two adjacent sides of a parallelogram drawn from point their resultant is represented by the diagonal of the parallelogram drawn from the same point. Draw a perpendicular Q R to O R produced. WebAccording to the theorem, where A, B and C are the magnitudes of the three coplanar, concurrent and non-collinear vectors, , which keep the object in static equilibrium, and α, β and γ are the angles directly opposite to the vectors. [1] Lami's theorem is applied in static analysis of mechanical and structural systems. WebVarignon’s Principle of moments (or the law of moments): It states, “If a number of coplanar forces are acting simultaneously on a particle, the algebraic sum of the moments of all the forces about any point is equal to the moment of their resultant force about the same point.” i.e. R × r = F 1 × r 1 + F 2 × r 2.
