Hello, I have a small question about moments and bending moments.
So, if I have a beam with a loading given by q (N/m) which is given as a function of x then what do these calculations get me?
\int xq(x) dx
\int (\int q(x) dx) dx
The first integral gives me the moment about a point because I...

For small deflections:
M=EI \frac{d^2y}{dx^2}
The Attempt at a Solution
To solve a problem like this, I think I was told I need to study the deflection and displacement of the beam.
If I said that the deflection at points x=0 and x=3L have to be 0...

Not too sure to be honest.
The Attempt at a Solution
Well, r1 cross product m v1 = r2 cross m v2
But, there is a force applied so I have to take that into account.
I was thinking,

Hello all. I have been trying to learn some Physics in my spare time and I came across Gauss' Law. I've been thinking about different cases and conditions and I have been confused by the actual meaning of Electric flux being 0.

i guess this thread belongs to GD.
is it true that early humans had copper based bloodand thus blue blood ????
