Thank you very much for the help! I can finish it now myself. I really appreciate the amazing responses, it has really cleared things up quickly.

Thanks Doc Al, so much appreciated. So, in essence, I treat it as two separate objects both in equilibrium in their own environments? Makes things simpler! I'm just not sure what the force is that is pulling point B - is it the gravitational force, or AB? I assumed gravitational force? I...

An object of mass 50 kg is supported at point A by five ropes as showin in the figure, and is in equilibrium. Determine the force in each rope. Figure is attached. Attempt at solution: FBD is attached. If the sides of the triangle formed by ROPE BD are in the relation of 5:3:4...

Do you mean that the downward force should be negative and the upward one positive? So mg = -147N? I'm sorry, I think I'm getting more lost now!

Do you have to divide the answer by two to get the tension, as it is shared on two sides (two hands pulling?)

Hi tiny-tim, thank you so much for replying. I knew I was going to make someone cry with my answer... Firstly, after having consulted my subject material, thanks I found the correct formula with regards to gravity, weight and work done: m/s2 x kg = N and yes, it doesn't mean I can just...

Homework Statement A muscle builder holds the end of a massless rope. At the end of the rope, a 15 kg ball is hung as shown in the figure. What is the tension in the rope if the angle \theta in the drawing is 4.5^{}o? Homework Equations g = 9.8m/s^{}2 F = mg Trigonometrical functions The...
