Three constant forces vector F1, vector F2 and vector F3 acting at a point object, are in equilibrium. Show graphically that they are in equilibrium.

Question

Three constant forces \(\vec{F_1}\), \(\vec{F_2}\) and \(\vec{F_3}\) acting at a point object, are in equilibrium. Show graphically that they are in equilibrium.

Answer 1

Let \(\vec{F_1}\), \(\vec{F_2}\) and \(\vec{F_3}\) be the three concurrent forces.

The same can be redrawn as the sides of a closed triangle (in magnitude and direction). It is observed that the order of all the forces is same so they are in equilibrium.
