To help you approach the physics experiment regarding rotational motion and equilibrium and finding the unknown mass, please provide a brief description of the lab setup or describe the key elements in the image you shared.

Hello Rahul,

To help you approach the problem, I would need more information about the lab setup and the specific measurements you have. Unfortunately, I am unable to access images or files directly, so I cannot view the Lab Drawing you mentioned. However, I can still guide you through the general process of solving such experiments.

1. Understand the setup: Familiarize yourself with the equipment and the arrangement of masses, strings, pulleys, and any other components involved in the rotational motion and equilibrium experiment. Take note of any known values, measurements, or variables.

2. Review basic principles: Make sure you understand the fundamental principles of rotational motion and equilibrium. For example, be familiar with torque, rotational inertia, and the conditions for an object to be in equilibrium.

3. Identify the unknown: Determine which variable or value you are trying to find in the experiment. Based on your description, you mentioned an unknown mass. Clearly define what you are looking to determine.

4. Set up the equations: Use the principles and known values to set up relevant equations. This might involve using torque equations, rotational equilibrium conditions, or other laws of physics that apply to your specific experiment. Be sure to include any relevant assumptions or simplifications.

5. Gather measurements: Perform the necessary measurements using appropriate tools, such as a ruler, scale, or timer, as needed in your experiment. Record these measurements accurately and consider any sources of error in your data collection.

6. Calculate the unknown: Use the equations you derived to calculate the value of the unknown mass. You may need to rearrange equations or manipulate variables to isolate the unknown value.

7. Check your solution: Validate your calculations and ensure your answer is physically reasonable. Double-check your work for any errors or mistakes.

Remember to follow any specific instructions provided by your lab instructor or the experiment manual. If you encounter difficulties, consult your lab partners, TA, or professor for additional guidance.

If you can describe the lab setup and provide specific details about your measurements and known variables, I can assist you further in solving the problem.
