This is a long problem. Apologies and thanks in advance.

Given: In the GTHTR300 plant, a fraction b of the coolant mass flow rate is bled off at the exit of the compressor to cool the turbine disks, shaft bearings and the electrical generator. Due to temperature limitations of the...
A rubber block is subjected to an elongation of 0.03in along the x-axis, and its vertical faces are given a tilt so that theta=89.3deg. Find epsilonx, epsilony, and gammaxy. vr=0.5. The block is 4 in along the x-axis and 3 in along the y-axis.
My solution
epsilonx = 0.03/4 = .0075...
I have an augmented matrix that I need to solve. I have broken it into a 4x4 matrix and a vector. As seen below.
A= 0 1 1 1; 3 0 3 -4; 1 1 1 2; 2 3 1 3
B= 0; 7; 6; 6
I have already worked the matrix out by hand using Gaussian Elimination and have obtained the solution below...
I've been working on a tooling Design project for a unique part, basically I'm taking a cast metal piece and drilling and reaming it to be used as an oil flow passage for a Harley Motorcycle. I.e. I'm the (student) engineer that is designing the jig/fixture device to be able to do the work...

Find 1: Cable force (line CD) so that the reaction at point B=0.
Find 2: Determine the Horizontal and vertical components of pin hinge at point A...
I need to find the Forve Vector (30N) as a Cartesian vector.
Given the information given, I believe that the angles of the Triangle are: 90, 32.37, and 57.63. This gives the projected vector in the x, y plane as 16.1 N.
The answer should be : - 13.2i - 17.7j + 20.3k.

Given:Second order ODE: x" + 2x' + 3x = 0
Find:
a) Write equation as first order ODE
b) Apply eigenvalue method to find general soln
Solution:
Part a, is easy
a) y' = -2y - 3x
now, how do I do part b? Do I solve it as a [1x2] matrix?
Imagine a cylinder running up and down the z-axis with a radius a
Now imagine a cylinder running up and down the y-axis with a radius a. Thoses are your cylinders.
combine the 2, and you will find an intersection from 0 to a on all sides
Now I think the limits you are looking for...
Given:
F(s) = (s-1)/(s+1)^3
Find:
f(t)
Solution:
Using the equation that when F(s) = n!/(s-a)^(n=1), L^(-1){F(s)} = t^n*e^(at)
So far I find that f(t) = e^(-t)*(-t^2+__)
The book says that f(t) = e^(-t)*(t-t^2)
How did they get the t?
