Hannah and Hillier introduce this as an alternative to resolving forces. If three forces keep a particle in equilibrium: [ \fracF_1\sin \alpha = \fracF_2\sin \beta = \fracF_3\sin \gamma ] Always ensure the angles are the opposite angles to the forces. A common mistake is using the included angle (360 minus opposite). The principles of friction and its role in machines 1
