Standard methods: pick a component of the system, draw a free body diagram for it showing all the forces, then write equations representing some of the balances that exist, such as horizontal forces, vertical forces and torques about some chosen axis.Butterfly41398 said:Homework Statement:: Find the tension in the rope

The answer is 280N but I don't have any idea hoe to get to the anseer. Atleast a hint would help.
Coplanar forces are forces that act on an object in the same plane or on the same surface. This means that all of the forces have the same direction and lie on the same flat surface.
To determine the equilibrium of coplanar forces, you must first draw a free body diagram of the object and label all the forces acting on it. Then, use the equations of equilibrium (sum of forces in the x-direction and sum of forces in the y-direction) to solve for any unknown forces or angles.
Static equilibrium occurs when an object is at rest and all forces acting on it are balanced, meaning the sum of forces in all directions is equal to zero. Dynamic equilibrium, on the other hand, occurs when an object is moving at a constant velocity and all forces acting on it are balanced.
Yes, coplanar forces can still be in equilibrium even if they have different magnitudes. As long as the sum of forces in all directions is equal to zero, the forces are considered to be in equilibrium.
The center of gravity is the point at which the weight of an object is concentrated. In equilibrium, the center of gravity must be directly above or below the point of support, otherwise the object will topple over. This is an important concept to consider when determining the equilibrium of coplanar forces.
