Objective in this lab we are using the force table to calculate the vectors. Using calculations show the magnitude and direction of the resultant of several forces acting
Theoretical Background vector is consist of both magnitude and direction. magnitude and directions with different forces take a single point, we call it resultant force. by calculating the additions of a vector, we can locate the resultant force. looking at the graph, first we have to plot our two vectors, call it A and B. A and B represent two separate force. then line our 60° and 90 square ruler. we match 90° square rule to the tip of Vector A, and match 60° square rule to the length of vector B. we drew a line from the tip of vector A parallel to to B. we make sure the parallel line of vector A is equal to the length of vector B. calculating vector A and B the new line that we constructed will be the resultant.

Vector A + Vector B= Resultant

Procedure
1. Set up a force table as in Fig. 1. Make sure the table is leveled before starting the experiment. Mount a pulley at the 20º mark on the force table and suspend a total of 100 grams over it. Mount a second pulley at the 120º mark and suspend a total of 200 grams over it. Draw a vector diagram to scale, using a scale of 20 grams per centimeter and determine graphically the direction and magnitude of the resultant…

• Force Table Essay

EXPERIMENT NO. 5 FORCE TABLE — ADDITION AND RESOLUTION OF VECTORS INTRODUCTION Forces add together as vectors. For example, if two or more forces act at a point, a single force may act as the equivalent of the combination of forces. The resultant R of the sum of two force vectors A and B is a single force which produces the same eﬀect as the two forces, when these pass through a common point (see ﬁgure). The equilibrant E is a force equal and opposite to the resultant. A vector may be broken up into…

units to their corresponding physical quantities. All engineers must use the same language in their communications, and one of these universal communication tools is the units of measurements. Physical quantities such as length, weight, time, speed, force, and mass are measured with standard units. Therefore the magnitude if a physical quantity is given by a number and standard unit of measurement. Examples: 5 meters, 60 kilograms. SI units are the international system of units (system international)…

Therein, force-free refers to a magnetic field for which the associated current density is exactly parallel, which is the definition we shall also use ∇×B=μ0j, j×B=0.These works consider one-dimensional (1D) collisionless…

There will then be two different experimental values, E1 and E2, but the true value may not be known. For this case, we will calculate the percentage difference between the two experimental values. Note that this tells nothing about the accuracy of the experiment, but will be a measure of the precision. The percentage difference between the two measurements is defined as Percentage…
