Smith, Augustus W. (Augustus William), 1802-1866 · New York : Harper · leaf 115
147. Prop. Required the condition of equilibrium of a cordacted upon by three forces. Let the forces Pj, P2,P3 be applied at the ex-tremities A and B of thecord ACB, and to a knotat C. Draw any lineCD in the direction ofthe force P2, and DN,DM parallel to CA andCB respectively. Incase ot… … 92 STATICS. 148. Cor. 1. If the cord be fixed at A and B, the reactionsof the points A and B take the place of the forces Pj and P3,and are equal to the tensions of the two parts of the cord respectively. 149. Cor. 2. If the force P2 be applied to a running knot orring, the points A and B being…
