@tpeter27 That is a good observation. I never thought of that as vibration, but it makes sense! #engmech

This picture shows the difference between damped and undamped vibration when you hit something with a hammer.#engmech

This is what happens when all factors that cause vibration was not calculated well enough. #engmech youtube.com/watch?v=T_LEwN…

At a distance of X1 (compression), you have potential energy,and at X2 (relaxation) you have kinetic energy. #engmech

@steffl1810 Along with instantaneous center of rotation, the gyroscope would also be an example of fixed axis rotation. #engmech

@rousha23 I am looking at the point right before losing balance and falling over. #engmech

Would walking on a tightrope be an example of instantaneous center of rotation? Fixed axis rotation? #engmech

Skidding on wet road is an example of general planar motion. youtube.com/watch?v=zKh873… #engmech

@rayscleveland @shockwave488 Maybe we could solve this using our knowledge of relative motion and a little extra help. #engmech

@johnsonc0681 Yeah! I found three things in my room which shows fixed axis rotation in a matter of 5 minutes. Easier than it seems. #engmech

The turning of a doorknob is an example of fixed axis rotation. #engmech

@wesley_schulte 60 degrees or 150 degrees.....depends on which way you look at it. #engmech

@NGFroynd Maybe the next time I eat lasagna i will try that and let you know how it went. :D #engmech

Lots of Impulse force was needed in order to cut and eat my overlooked, extra crispy lasagna for dinner. #engmech

@mariautpadel I am referring to the part in between both of them. It is a constant velocity of 15 mph. #engmech

@masonDYNAMICS Thats a good example! I didn't think of that! #engmech

@rayscleveland I didn't even notice that. Good catch.

How much kinetic energy do you think this car has if it was moving at a constant speed of approx. 15 mph? #engmech

@6murray11 I get what you are saying. I think that would hurt a lot more than a penny. Hope no one ever has to go through that.

@2013papanthe you can find the accelerationas long as you have the total mass of each side. I found this online. answers.yahoo.com/question/index…
