...Triangle of Forces is also true, viz. that If three forces acting at a point be in equilibrium they can be represented in magnitude and direction by the sides of a triangle taken in order. Let the three forces P, Q, and R, acting at a point 0, be in equilibrium. Measure off lengths OL and... ## The Architect's and Builder's Pocket-book of Mensuration, Geometry ...

...squares of the other two forces. Tlic Triangle of Forces. — III. If three forces acting on a point be represented in magnitude and direction by the sides of a triangle taken in order, they will keep the point in equilibrium. Thus let P, Q, and V.

...momentum. But CO, OA, OB are equal and parallel to the sides of the triangle CO A taken in order. Therefore if three forces, represented in magnitude and direction...by the sides of a triangle taken in order, act on a particle, the particle will remain at rest ; or, if already moving, it will continue in motion along... ## The Mechanics of Daily Life

...opposite way, as at (rf). This result may be summed up thus, " If three forces acting at a point can be represented, in magnitude and direction, by the sides of a triangle taken in order, the forces will be in equilibrium;" that is, will exactly balance each other. The direction in the... ## A Text-book of Statics

...must act in their plane and be equal and opposite to the third. (3) J[f three concurring forces are represented in magnitude and direction by the sides of a triangle taken the same way round, the resultant is zero and the forces are in equilibrium.
