See note below
Create a model of the hollow cylinder sector shown. Build the model such that no matter what dimensions are given for L and Theta, the model will oriented with the Absolute CSYS at its center of mass. Hint: Use expressions, use symmetrical extrusion. (Note: In order to get NX to return Theta as radians, use RADIANS(Theta).
Verify that the center of mass is:
Xcbar, Ycbar, Zcbar = -0.00000000000, 0.00000000000, 0.00000000000
For several values of R, L, and Theta.
NOTE: Change the 38.1972 to 2/3 and use theta in radians (the 38.1972 is 2/3 * 180/pi).
Something like: 2/3*sin(theta)*(R2^3-R1^3)/(radians(Theta)*(R2^2-R1^2))
