So the formula is an original formula? Is it possible to explain and derive it in simple terms? I have checked up the wikipedia on 'Bending' and the equations and explanations are all non-human level. LOL

There is an experiment to determine the Young's Modulus of the wood which involves bending it. The equation used to calculate it is like this E=WX3/4ZDY3 Where D=amount of bending W=force (N) which causes the bending Z=width of the wood Y=thickness of the wood X=horizontal distance between the...

Because Alice throws instead of releases, an extra force is exerted downwards?

Homework Statement Alice and Bill are at the top of a building. Alice throws her ball downward. Bill simply drops his ball. Which ball has the greater acceleration just after release? Homework Equations force, F=ma and F=mg The Attempt at a Solution Alice: F=ma+mg=m(a+g) Bill: F=mg...

OH... Oh sorry Sir, forgive my stupidity. Yes you have solve the problem! Since day 1... Thank you Sir CWatters for accompanying me this whole week. I appreciate it. :k Though in the end, I still can't figure it out myself...

Do you mean like this, Sir? Because I don't really understand...

Do you mean tilting the whole table, Sir? This is the only way I can think of... and it's the same as decreasing the height of one of the two fixed points (P or Q), if I am not mistaken.

There are 4 types of fundamental forces: Gravity, Electromagnetic Force, Strong Nuclear Force and Weak Nuclear Force. The latter two are, if I am correct, involved particularly in interactions between elementary particles. So Sir, do you mean electromagnetic force? I have thought about that...

OK gravity is always directed towards the centre of the earth.

Homework Statement http://cgscomwww.catlin.edu/sauerb/AP12/AP12_Labs/AP12_Lab_4_Forces_files/image002.jpg My experiment is like this picture found in the net. The weight in the middle is called R in my experiment, while the left one is P and the right Q. Now there is one question asked, the...
