A solid 4340 HR Steel tie rod of length Lrod = 850 mm is employed to compress a 6061-T6 aluminum
bushing of length bushing = 625 mm as shown. The tie rod has a solid circular cross section with diameter
drod = 22.5 mm. The bushing has a hollow circular cross section with outer diameter do = 75 mm, inner
diameter di, and wall thickness t. If F = 50 kN, determine the minimum wall thickness of the bushing based
on the below design requirements:
⚫ the displacement of the bottom of the tie rod with respect to the fixed horizontal surface may not exceed
Stotal = 1 mm
⚫ the normal stress of the bushing may not exceed the yield strength of the bushing material
