CGN 3421 Computer Methods Fall 2000 CGN 3421 lab6_cmf01.fm page 1 of 2 Lab #6 10/10/01 Matrix Operations: Given the following system with unknowns x, y, z : 1) Find the inverse of the coefficient matrix above using Gauss-Jordan Elimination by hand: 2) Solve for x, y, z using the inverse you just found 4) Solve for x, y, z with the same coefficient matrix but with a new solution vector. Use the inverse from the previous problem 5) Confirm your answers in Mathcad Confirmation problem for HW#6: The solution to homework #6 will be difficult to confirm without running a problem with a known solution first. Some of you have taken or are taking a class that would help you out. Others have not yet taken that class. So, the following is the input and proper solution to the truss homework problem with different values than you have been given. INPUT: A=5 in2, E=29000 ksi, F(1) = -20 kips, F(2) = 100 kips, F(3) = -150 kips OUTPUT : r(1) = -0.00662 r(2) = -0.00310 r(3) = -0.09931 (all in inches) Hints for HW#6 Your function that calculates displacement should be given A, E, L, F as input
