In my case, I think it is the resistance of deflection. However, when I search online that is also the definition for Young Modulus. Yet there's these two different equations which is confusing.

Just want clarification on two equations. So basically, I want to calculate the time period T of the complete oscillation of a cantilever. I use this equation. Is E equal to young's modulus or is it equal to stiffness? If it is equal to stiffness, can I use this equation to calculate the...

So for my curriculum I have to do a physics experiment and write a 2000 word essay on it. For my experiment, I'm planning to wrap a string with a ball attached to it n number of times around a pole and measure the time taken for it to unwind by changing variables such as the radius of the pole...

Homework Statement Homework Equations K.E = p^2/m The Attempt at a Solution [/B]

I'm not sure how to find out, I'm really sorry. All I know: volume of larger container : volume of smaller container 3456 : 1458 Simplified: 64 : 27 Which is where I got stuck. I don't know what to do from there.

Homework Statement Homework EquationsThe Attempt at a Solution I tried cross multiplying but obviously that is not the case. These types of questions are the ones I always lose marks in. Any help would be appreciated.

I looked into it and I understood now, thanks for the help.

Oh, now I understand! I always have a problem with reading the question properly. Thank you both!

The equation e= mgh is for the second question. The answer to the first question is 300N, but I am not understanding why.

Homework Statement Homework EquationsThe Attempt at a Solution I need help with the second question, I did the first one correctly. My pre board is on Monday so please help.

I checked the question in my book and yes, it is weight. I am really sorry.

I meant force! And sorry, I'll do that next time.

Homework Statement A rocket of force 1000N is propelled upwards by a thrust of 1800N. The air resistance is 500N. a) Work out the resultant force on the rocket. A bungee jumper of mass 60kg jumps from a bridge tied to an elastic rope which becomes taut after he falls 10m. Consider the jumper...
