Problem: Distance Formula (distance.c)
To test their idea, the Math Academy would first like a short program that computes the distance between two points on a Cartesian Plane. The students are expected to work their problems on paper and then compare their answers to the answers generated by your

formula I d3t/8 (see Case 22, Appendix D), and
therefore the section modulus may be obtained from the
formula S d2t/4.
At what distance x from the free end does the maximum
bending stress occur? What is the magnitude max of the
maximum bending stress? What is the ratio of the maximum

→ Q is the main variable.
(∵ V, I, b : const. in rectangular cross section )
∴
→ alternative Q :
→ τ in rectangular beam varies quadratically with the distance y1 from the neutral axis. (∵ V, I, h : const )
