Moment of a force (torque) measures the tendency of a force F to make a rigid body rotate about a fixed axis directed along a point. I have to find an appropriate pivote point in the system to delete unknown forces.
MO = rFsinθ = Fd
The moment (torque) Mb of the force T about B is 0 since this...
Yes, I was referring to torque. Would it apply to the spring force? I´m sure I need to calculate the spring constant first. If I choose B as pivote then tension on the left side would be eliminated and I would have to work with the weight and the y component of the spring force.
Which would be...
Are you thinking about using Hooke's Law on the right side? I was thinking about calculating the spring constant in lab and find a way to determine its force in terms of k, however I can´t think of a way to "connect" the angle α in both sides of the system.
I would use statics equation in x and y but the tension on the the left side is an unknown force and the spring force also.
How should I relate the angle α with the tension on the left and the spring force?

I have a project from my Mechanics class which consist on building the system on the picture. It has a spring, cable and a protractor. I have to do an approximation of the mass and weight of the object that is put in the...
