Static Equilibrium Problem involving Moments

Click For Summary
SUMMARY

The discussion focuses on solving a static equilibrium problem involving moments, specifically addressing the conditions where net torque and net force are both zero. Participants emphasize the importance of correctly identifying the axes of force, particularly distinguishing between the x-axis and the line of the 80Kg rod. The forces involved include the weight of the rod (80Kg), the mass (10Kg), and the tension (T) from the cable, alongside the force component (F_y) from the wall at point A. The solution requires setting up equations based on these forces and torques to find the unknowns F_x and T.

Equations: Net torque=0=Net force
I believe this is a static equilibrium question but can't figure out how to do it

The net force on the x-axis must be zero. What equation can you make from this fact?

Also the net torque is zero. Take the torques around the A point. What equation can you make?

Solving these two equations with two unknowns (F_x and the force from cable ) will get you the result.

this is what i have split the forces as till now,
somehow i can't get them to cancel
 
You get involved with the forces along the line of the 80Kg rod, that's not what you should do, the x-axis is not the line of the 80Kg rod, the first picture at OP shows which are the x -axis and the y-axis.

In the y-axis you got the weights of the rod and the mass m, 80Kg and 10Kg respectively (and the F_y component of the force from wall at A).
In the x-axis you got F_x and the tension T from the cable.

ah got it thank you
