Equilibrium Problem(Tension of each cord)

[durty53]

I have a problem..I cannot solve this one..the angles are on the side.. I don't have any idea..any answers would be much appreciated!

Indicate the forces acting. Apply the conditions for equilibrium.

 

[durty53]

the weight(W) of the suspended body is 150N

 

[Doc Al]

the weight(W) of the suspended body is 150N

OK.

Consider the forces acting at the connection point. Name them.

 

[durty53]

The book said that I should find the tension in each cord if the weight(W) of the suspended body is 150N

 

[Doc Al]

The book said that I should find the tension in each cord if the weight(W) of the suspended body is 150N

Yes. Label the cord tensions T₁ and T₂.

Since there's equilibrium, what must be the net force?

 

[durty53]

Yes. Label the cord tensions T₁ and T₂.

Since there's equilibrium, what must be the net force?

the net force must be zero

 

[Doc Al]

the net force must be zero

Good!

Now express that mathematically. Write equations for the vertical and horizontal force components.
