Finding magnitude & direction in equillibrium

In summary, an object in equilibrium has three forces exerted on it, including a 28-N force at 90° and a 65-N force at 60°. In order for the object to remain in equilibrium, the magnitude and direction of the third force must be such that the net force in all directions sums to 0N.

An object in equilibrium has three forces exerted on it. A 28-N force acts at 90°, and a 65-N force acts at 60°. What is the magnitude and direction of the third force?

I HAVE NO IDEA HOW TO DO THIS...
PLEASE HELP!

If the object is in equilibrium, its not accelerating in any of the referred/assumed directions. The net force should sum to 0N in all such directions.

thank you so much!
that was exactly what I needed to know
 

What is equillibrium in physics?

Equillibrium in physics refers to a state where the forces acting on an object are balanced and the object is not accelerating. This means that the net force on the object is equal to zero.

How do you find the magnitude of forces in equillibrium?

To find the magnitude of forces in equillibrium, you can use the equation Fnet = 0, where Fnet represents the net force acting on the object. This means that the magnitude of the forces in equillibrium must be equal and opposite.

What is the difference between magnitude and direction in equillibrium?

The magnitude of forces in equillibrium refers to the size or strength of the forces, while the direction refers to the orientation or angle of the forces. In equillibrium, the magnitude of forces must be equal and the direction must be opposite.

How do you determine the direction of forces in equillibrium?

To determine the direction of forces in equillibrium, you can use a force vector diagram. This diagram shows the magnitude and direction of all the forces acting on the object. In equillibrium, the forces must be balanced, so the direction of one force will be opposite to the direction of the other forces.

Why is it important to find magnitude and direction in equillibrium?

It is important to find the magnitude and direction of forces in equillibrium because it allows us to understand the stability of an object. If the forces are not balanced, the object will start to accelerate, which can lead to dangerous or unstable situations. By finding the magnitude and direction in equillibrium, we can ensure the safety and stability of objects and structures.
