I am sorry. I didnt quite follow you. How do i know the length of GA? Do you mean GC?

Thanks for the quick reply! Yes. I did that. If the forces are in equilibrium they should meet at one point. But still I can't calculate the answer with just one force and one angle known... I am sure i am overlooking something... Here is a diagram i came up with... I need to find one of the...

Homework Statement A uniform rod AB of weight 20N is hinged at a fixed point A. A force acts at B holding it in equilibrium at 30 degrees to the vertical through A. calculate force acting at B if it is perpendicular to the rod. The Attempt at a Solution I figured that the angle between...

Ah... Its all good now there was a little mix up i nthe equation but I figured it out. Thanks a lot again TIM! I don't know how you do it but you be tha man!

Oh... I understand now! *facepalm* I must be so dumb. Anyway thanks a lot guys! Really impressed. :approve:

I came up with the exact same strategy i.e. resolving the firces into components but you guys lost me on afrocod's third post where he seems to be using T cos 20 + T cos 40 = 2 but cos 40 = .766 not .64 which is cos 50 EDIT: Oh i put in cos 40 and it gave .35 the correct answer... Thanks a lot...

I am having problems with the same question can you explain a bit more on how you reach the answer?

Homework Statement In a regular hexagon, ABCDEF, forces of magnitude 2N, 4N, 3N and 2N act along the lines AB, AC, AD and AF respectively. Find the equilbrant of the given forces and verify that is equal and opposite to their resultant. The Attempt at a Solution I realized that AB + BC...
