Lami’s Theorem
If three concurrent forces acting on a body keep it in equilibrium, then each force is proportional to the sine of angle between the other two forces. If three concurrent…
Free-Body Diagram
A free-body diagram is a sketch of an object of interest with all the surrounding objects stripped away and all of the forces acting on the body shown. The drawing…
Equilibrium for Coplanar Forces | Condition of Equilibrium Coplanar Forces
Equilibrium for Coplanar Forces | Condition of Equilibrium Coplanar Forces: Forces in equilibrium mean that they are balanced. Coplanar forces act in the same plane. Two balanced forces are equal…
