Find the magnitude of friction force. Whether the block will move, if a horizontal force of 15 lbf is applied. Find the magnitude of horizontal force to set the block in motion.

Question

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: de f(t,c) = = 30-3c Where c is the concentration and t is time.
