In summary, the conversation discusses a complex motion problem involving a fixed bar and a rotating blue bar. The angle theta, which represents the rotation of the blue bar, is defined and the law of energy conservation is mentioned as a method for finding the relationship between theta and angular velocity. The use of computational tools is suggested due to the difficulty of computing the integral.

I don't think the bar will be in circular motion. The motion is rather complex since the string 1 is involved. And what is theta anyway? You haven't defined it yet.

First of all, this question is not homework, Unknowingly was moved to this section!

Thanks for reply
Suppose string 1 is a solid and fixed bar; not a string actually :D, and on which the blue bar can freely rotate.

As for theta, as I said, it's how many degrees the blue bar rotates after string 1 is cut, in other words, it's the angle between the negative x-axis and the blue bar.

Use the law of energy conservation to find the relationship between angle theta and angular velocity, and then compute the integral to find angle theta w.r.t. time t. The integral is hard to compute, so use wolframalpha (http://integrals.wolfram.com/index.jsp) or any other tool. I believe the result won't look nice at all.

hey this is a typical textbook problem.
 

1. How do you identify a mechanical problem?

Identifying a mechanical problem involves conducting a thorough inspection of the mechanical system and its components. This can include visual checks, listening for unusual sounds, and using diagnostic tools like pressure gauges or computer diagnostics.

2. What is the first step in solving a mechanical problem?

The first step in solving a mechanical problem is to gather information and identify the root cause of the issue. This may involve speaking with the owner or operator of the system, reviewing maintenance records, or conducting tests and measurements.

3. How do you troubleshoot a mechanical problem?

Troubleshooting a mechanical problem involves a systematic approach of identifying potential causes and ruling them out one by one. This can include checking for loose or damaged components, testing electrical connections, and using diagnostic equipment.

4. What are common solutions for mechanical problems?

Common solutions for mechanical problems can vary depending on the specific issue, but some common solutions include replacing faulty components, repairing damaged parts, or adjusting settings or controls. In some cases, a redesign or upgrade of the mechanical system may be necessary.

5. How can you prevent mechanical problems from occurring?

Proper maintenance and regular inspections can help prevent mechanical problems from occurring. This includes following manufacturer's recommendations for maintenance and replacing components before they fail. Additionally, proper operation and training for operators can also help prevent mechanical problems.
