Consider the structure shown in the following figure, which includes two identical towers, a main cable whose unstretched length is 110 m handing between them, and two side cables with negligible weights (so that they can be modeled as massless springs). The side cables are pretentioned so that the net horizontal force on a tower iszero. The mass per unit length of the main cable is 10 kg/m and EAo = 1000KN. Thehorizontal distance between the two towers is 100 m. The angle del is 60°. By design the total horizontal load on each tower is zero. Find
A)The horizontal and vertical loads exerted on each tower by the main cable
B)The minimum mass M of the counter weights. Note that the counter weights are blocked from moving in the horizontal direction
4th Order Rurka-Kutta Method
This assignment will expand your skills on using Excel to perform some numerical
analyses and plot your results. It is a means to familiarize you more with basic features in
the spreadsheet.
Preliminaries:
a. Start a new file called R-K.xlsx (for this exercise, you may use the work you did
in class but please be careful not to delete what you already have)
b. Plan ahead
Exercise 1:
Using the 4" Order Ruga-Kutta Method that we recently learned, evaluate the following
ordinary differential equation (ODE):
dx
f(t, x) =
= x+t²
dt
At the initial position, X= 0, the time is = 0.1 minutes. Using a step size of, h = 0.05,
what is the time spent to reach a position that is equal to 17 (Hint: use a O and b 1)
Exercise 2
Using the 4th Order Ruga-Kutta Method, solve the following problem:
The concentration of a certain non-reactive (conservative) chemical is given as a function
of time by:
