## cartesian coordinate system

[kär′tē·zhən kō′ȯrd·nət ‚sis·təm]
(mathematics)
A coordinate system in n dimensions where n is any integer made by using n number axes which intersect each other at right angles at an origin, enabling any point within that rectangular space to be identified by the distances from the n lines. Also known as rectangular cartesian coordinate system.

However, for the bending stress in the X-Y plane under off-axis loading, the result is significantly different: the ratios of the axial direct stress and the bending stress are 46.44% and 53.56%, respectively.
As shown in Table 3, in the X-Y plane, the axial direct stress possesses 100% of the superimposed stress in the on-axis loading case; however, under an off-axis load, the bending stress and the axial direct stress play nearly equivalent roles in the maximum superimposed stress.
In addition, in the X-Z plane, it shows that the superimposed stress in the off-axis loading case is equal to that in the on-axis loading case; in contrast, in the X-Y plane, the superimposed stress in the off-axis loading case is approximately 1.944 times that in the on-axis loading case.
For the HFRP lower chord members, the off-axis load is the critical loading condition controlling the X-Y plane stress.
