Obviously I am approaching this problem from multiple angles. Based on my math and understanding I feel that my answer is correct. I was hoping someone could either correct me or confirm with me. If you are going to correct me please have a valid explanation with a mathematical backup to prove...

Oh and period is T = 1/f, T is period

For part a you would need to use the potential energy equation involving the spring constant. which is U = 1/2kx^2 set this equal to kinetic energy and solve for velocity. You will also need to know the distance it is stretched. F = kx, F = mg you have these so solve for x. Now to find the...

Yes, I stated that in my response, but since mg is in the Y direction, vertically as you put it and the system is in a 'static equilibrium' there is also a tension T-y in the opposite direction of the force due to gravity. Because of this fact the forces in the y why direction are irrelevant to...

Alright well this is how I am seeing it. T-2 - T-1 = 0 or T-1 + T-2 + mg = 0 Since there is no forces acting in the Y direction, we are left with the two x components which are supporting the rod, thus the force due to gravity is irrelevant seeing as it is in equilibrium, it cancels out...

Alright well this is how I am seeing it. T-2 - T-1 = 0 or -T-1 + T-2 = 0 (these are the x components) Since there is no forces acting in the Y direction, we are left with the two x components which are supporting the rod, thus the force due to gravity is irrelevant seeing as it is in...

Yes, I understand. I have summed up the forces and chosen arbitrary numbers but the tension on the ropes are specific to a certain mass of the rod. I have multiple answers and am unclear on the correct answer and process. And my teacher starts a problem and says you should be able to figure it...

You do understand in order to analyze those factors, one would need to know lengths and mass right.

So are you saying it is a problem of which one would need to choose arbitrary numbers to calculate the angle?

Here is a link with a picture and description.

Homework Statement A uniform rod is supported by two strings. The string on the left hand side is horizontal. The string on the right hand side is at 30 degrees with respect to a straight line going from the end of the bar to the ceiling. If you had a straight line going from the end of the...
