...COR. If the components be represented in magnitude and direction by the sides of a parallelogram, the resultant is represented in magnitude and direction by the diagonal of the parallelogram. DBF. Forces may be represented by lines parallel to them in direction and proportional to them in magnitude.... | |

...COR. If the components be represented in magnitude and direction by the sides of a parallelogram, the resultant is represented in magnitude and direction by the diagonal of the parallelogram. 56. PROP. Any force represented in magnitude and direction by one side of a triangle, is equivalent... | |
