Triangular law of forces
WebAug 8, 2011 · Resolve the given forces horizontally and calculate the algebraic total of all the horizontal parts or Σ H. The resultant force R of all the given forces can be expressed as: R = (Σ V)^2 + (√ H)^2. The inclination of the above resultant force will be at an angle Ɵ with the horizontal component and may be expressed as: tan Ɵ = √ΣV / √ΣH. WebThe resultant force FR acting at the point P is the diagonal PB of the parallelogram. The magnitude of the resultant force F R can be determined by measuring the length of the diagonal PB and multiplying it by the scale …
