Given the elevations of five points that are equally spaced by distance 'h' in a horizontal direction, derive a general expression to determine the second derivative of slope at the central point with an accuracy of order h3
If elevation is given by 'z' and horizontal distance by 'x', use...
Ok thanks cos i was getting worried i wasn't getting the same answers for P and D that is given in one of the tutorial books that I'm using where my answers just differed by column arrangements
I understand this but is there more than one answer for D?
Using my example in the 1st question i could get
1 | 0 | 0
0 | 3 | 0
0 | 0 | -4
or
1 | 0 | 0
0 | -4 | 0
0 | 0 | 3
etc..simply by assigning a different first eigenvalue from either 1, 3, or -4
Hey guys, I'm having trouble trying to understand how the diagonalised matrix is produced
e.g.
A =
1 | 3 | 0
3 | -2 |-1
0 | -1 | 1
I've calculated the eigenvalues to be 1, -4, 3
My question is, how do we know that
D =
1 | 0 | 0
0 | 3 | 0
0 | 0 | -4
and not any other combination of 1...

Homework Statement
The rocket sled starts from rest and accelerates at a = 30 + 2t until its velocity is 400m/s. It then hits a water brake and its acceleration is a = -0.003v^2 m/s^2 until its velocity decreases to 100 m/s. What total distance does it travel?

How would i calculate the stress and strain with the results from a lab below:
Steel’s original diameter: 8.00 mm
Steel’s original length: 49.96 mm
Steel’s final diameter: 4.64 mm
Steel’s final length: 63.17 mm
Steel’s maximum load force: 26.43 kN
I also have an MS Excel table of time, laser...
