1 Suppose The Off Axis Layers In The Tube Of Failure Example 1 Were At 30 Instead Of 20 A What Would Be The Axia 1 (78.46 KiB) Viewed 12 times
1. Suppose the off-axis layers in the tube of Failure Example 1 were at ±30° instead of ±20°. (a) What would be the axial load capacity of the tube? (b) Would the failure mode and the layers that control failure be the same as when the fibers were at ±20°? To answer this question you essentially must redo the example problem, starting with the stresses due to P = 1 N (i.e., beginning at Table 9.2 and proceeding).
