The Triangle of forces (Engineering Science) Lab Report

The Triangle of forces (Engineering Science) - Lab Report Example Figure 2 on the left shows a space diagram in which only the lines of action of the forces are shown. On the right is the force or vector diagram in which sides of the triangle represent to scale the magnitude and also the direction of the three forces. Forces in the space diagram are designated by capital letters placed in the spaces on each side of the force, e.g. the force labelled ab in the force diagram is called AB in the space diagram. Note that the force AB emanates outward from the node. A force designated BA would be the opposite direction. Figure 3 on the left shows a space diagram (the position of the strings) in which only the lines of action of the forces are shown. The combination of weights (forces) taken are 70g, 70g, and 90g. On the right is the force or vector diagram in which sides of the triangle represent to scale the magnitude and also the direction of the three forces. The force 70g () is represented by vector in the, the force 70g () is represented by vector in the, and the force 90g () is represented by vector in the. From figure 3, it can be seen that the three forces,, and in equilibrium forms a triangle (approximately). The triangle is not closed because of measurement errors. Figure 4 on the left shows a space diagram (the position of the strings) in which only the lines of action of the forces are shown. The combination of weights (forces) taken are 90g, 70g, and 90g. On the right is the force or vector diagram in which sides of the triangle represent to scale the magnitude and also the direction of the three forces. The force 90g () is represented by vector in the, the force 70g () is represented by vector in the, and the force 90g () is represented by vector in the. From figure 4, it can be seen that the three forces, , and in equilibrium forms a triangle (approximately). Figure 5 on the left shows a space diagram (the position of the strings) in which only the lines of action
