I am wondering if can the colour of a liquid be related to its density?

think of a engine. it has a flywheel and a rod connected to it. a string had been totally wrapped around the rod and a mass is hanged from the very end of the rod. the system is in equilibrium. but as the engine starts to rotate, the rod with rotate as well and cause the hanged object to go...

Would it be right if I use torque and angular velocity to find the output power and use the slope of the p vs v diagram for the input power and find the efficiency using those two?

and I have to make different measurements and I have to use a graph to analyze the work but which graphs should I use? thanks again

it has a flywheel but I didn't get what you said about torque, is there a formula for that? thank you

hello, I had made an DIY alpha type Stirling engine for my physics project and now I have to write an report about the relationship between the heat given to the engine and the motion of the wheel. I had searched a lot about Stirling engines and I learned about work, energy, efficiency...
