So for the deflection I found a formula P.L^3/(48.E.I)
The right answer should be 3,33cm
I calculated Ix and put it there to the formula and what I got is 3,39cm.
Is my work at least a bit correct?
I decided to solve it on my own. But I have one question. How could I calculate the Moment of Area of the cross-section of the beam? That's the only thing I have no idea what it is and how to calculate it.
I'm a high school student and we made this experiment at school and I just wanted to know if I could calculate it with some formula. But I think that I don't have enough knowledge to solve it by myself. Is there anybody who would like to solve it for me please?
The beam is supported on the ends of it.
Length of it is 100cm. The other two dimensions are 5cm and 0,5cm. The cross section is rectangular.
I'm a bit confused. Hopefully I wil somehow solve it.
I tried to use F/S = E.ε to find the new length after deformation and than use pytagoras theorem in right angled triangle to find how much did the middle point lower.
But it was said to me that my method is wrong and that there exists some formula to solve it. Can you please tell me where could...

Hello, i have a sequence {1,2,13,62,313...} and I have to find out the rule for n-th number. I've found out that every next number is five times bigger but then is added or subtracted 3. For example 1x5 -3 = 2 and 2x5 +3 = 13 and so on. Can you please give me some advice how to create the...
