Question

Math and Physics: Help needed!

Answer 1

@UnkleRhaukus maybe?

Answer 2

just not sure how to get the equations. once i have them i can do all the rest..

Answer 3

First work out the geometry/trig.
Take moments about the hinge, which eliminates the reactions, and the axial force F on the strut.
The rest will come easy.

Answer 4

yea im not sure about the moments. so if i take the moment (Fd) about the hinge, then i can neglect the Rh and Ry? im just pretty lost...

Answer 5

This is the idea.
Since the three forces Rx , Ry and F pass through the hinge, the distance is zero, so the moment is also zero. You don't really ignore them, but they disappear!
You will need to work a little on trigonometry to get the moment arm of T.
You will need the cosine rule, as only one angle is known, but the adjacent sides of the 60 degree angles are known.

Answer 6

After that, you'll need the sine rule to find the moment arm of T.

Answer 7

@chemENGINEER Did you manage to find T?
