Unformatted text preview: from the scale drawing. The size (as measured with a ruler) is 13 N and the direction (as measured with a protractor) is 23 degrees from the 12N force. 4. This exercise msut be solved using a scale drawing. In this case you need to find the force that is needed to connect the tip of the second arrow to the tail of the first. As shown in the diagram, the three forces form a closed figure. This means that the total (or net) force is zero. Note that this force is equal in magnitude and opposite in direction to the sum of the first two forces. The magnitude of this force (as measured with a ruler) is 5 N and its angle (as measured with a protractor) is 37 degrees east of north....
