Chapter 11, Problem 11.6.6P
A circular aluminum tube with pinned ends supports a load P = 18 kN acting at a distance e = 50 mm from the center (see figure). The length of the tube is 3.5 m, and its modulus of elasticity is 73 GPa.
If the maximum permissible stress in the tube is 20 MPa, what is the required outer diameter d2if the ratio of diameters is to be d1/ d2= 0.9?

A spring package with two springs and an external force, 200N. The short spring has a loin of 35 mm. Constantly looking for spring for short spring so that total compression is 35 mm (d). Known values: Long spring: Short spring:C=3.98 N/mm Lo=65mmLo=87.4mmF=c·fTotal compression is same for both spring. 200 = (3.98(c1) × 35) + (c₂ × 35)
200 = 139.3 + 35c₂
200 - 139.3 = 35c₂
60.7 = 35c₂
c₂ = 60.7/35
Short spring (c₂) = 1.73 N/mm
According to my study book, the correct answer is 4.82N/mm

The ratio of the longer side of the wire to its shorter side is 1.5, and the ratio of mean diameter of spring to the longer side of wire is nearly equal to 6.
