law of vector addition. The vectors . A . and . B . can be drawn with their tails at the same point. The two vectors form the sides of a parallelogram. The diagonal of the parallelogram corresponds to the vector . C = A + B, as shown in Figure 3.2b. C = A + B B A (a) head to tail . A B C = A B (b) parallelogram . Figure 3.2a Figure 3.2b
parallelogram law of addition (and the triangle law). Equivalent Vector: V= V1+ V2(Vector Sum) Ex: displacement, velocity, acceleration, force, moment, momentum
Construct a parallelogram with sides in the same direction as P and Q and lengths in proportion. Graphically evaluate the resultant which is equivalent in direction and proportional in magnitude to the diagonal. Trigonometric solution. Use the law of cosines and law of sines to find the resultant.
Major characteristics of a force vector, (a) the parallelogram law (the resultant of two force vectors is found by drawing a parallelogram with its diagonal becoming the resultant), and (b) the principle of transmissibility (two force vectors with the equal
This textbook covers all the standard introductory topics in classical mechanics, including Newton’s laws, oscillations, energy, momentum, angular momentum, planetary motion, and special relativity.
Forces are drawn as directed arrows. The length of the arrow represents the magnitude of the force and the arrow shows its direction. Forces on rigid bodies further have a line of action. Forces (and in general all vectors) follow the parallelogram law of vector addition.
parallelogram law for vector addition because, in a geometrical interpretation of vector addition, c is the diagonal of a parallelogram formed by the two vectors a and b, Fig. 1.1.1b. The following properties hold for vector addition: ab ba … commutative law abc abc … associative law 2. The Negative Vector:
