I apologize for my multiple recent posts, but I'm having pre-exam stress, so even the simplest things seem nearly impossible. Haha..

Homework Statement


Handwritten physics problem: a bar hung from two cables, cable 1 at a 20° angle to the bar, cable 2 horizontal, with a hanging mass of 80 kg below the bar, labelled T for tension.

Note that connection point between the bar and the cable is not a pulley.


Homework Equations


F=ma


The Attempt at a Solution


The problem seems to be pretty straightforward, but would T=800N? (We use 10 m/s2 for acceleration due to gravity.) And also, what would clue me into whether the bar pushes or pulls on the ropes?

Thanks!
 
Draw a free body diagram of the hanging mass. You should have the tension, weight, and force the bar exerts. Split the tension into horizontal and vertical components.

The mass is in equilibrium so the left/right and up/down forces must be equal that should clue you in as to what direction the bar force is exerting.

It should be pretty straight forward to solve for tension now also.
 
Sorry for the late reply, but would this be the correct way to approach this?
