Unformatted text preview: AE 221 Aerospace Structures II Spring 2004 Chapter 1 Review Practice Problems Using the package(s) of your choice (Mathematica, Maple, Matlab, Gnuplot, ), solve the following problems, which are typical of those you will face in AE 221. 1. Plot ( ) 4 x 6 2 / 1 x- x 3 x 2 3 + + + stp on 1 x , where ( ) < = x x 1 x x x x for for stp is the so-called Heavyside (step) function. 2. Plot (on the same graph and with the appropriate legends for the three curves), ( ) ( ) ( ) x a x x 3 a x f cos sin , + = on 1 x , for 2 1 a , , = . You may also make up a title and axis-labels. 3. Compute [ ] ( ) ( ) dx a x f x a x f 2 1 L a g L 2 2 + = , , , , where ( ) a x f , has been defined in problem 2. Plot [ ] 1 L 3 a g = , . 4. Solve the following linear system = 2 3 2 1 4 2 2 2 L 4 L 2 C C C L 3 L 2 L 2 L 3 L 2 L 3 1 5. Solve the following boundary value problem and plot the solution Differential equation: ( ) ( ) 3 x x w 4 + = on 1 x Boundary conditions: ( ) ( ) ( ) ( ) 1 w 1 w 1 w w = = = = ' ' , , ' , 6. Plot (from an appropriate angle and with appropriate resolution) ( ) ( ) ( ) z 5 e 2 z yz 2 z y q y cos sin , + = on z 3 y 1 , 7. Let ij be the identity tensor.
