...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... | |

...are equal and parallel to the sides of the triangle COA 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... | |

...several forces which are applied at the several angles as shown. These forces being in equilibrium may be represented in magnitude and direction by the sides of a triangle, as a, b, C, Fig. 123. Since the forces at <7, Fig. 122, including the strains in the bars, are in equilibrium,... | |

...with adjacent sides equal, such sides would be unequal. Now, it is a rule in mechanics, that if two forces acting at a point be represented in magnitude and direction by the sides of a parallelogram, the resultant force will be represented in magnitude and direction by the diagonal of... | |

...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. (4) Hence, if three concurring... | |
