Q.4.1.L The segment AB of the steel torsion bar is acylindrical tube of constant 2-mm wallthickness. Segment BC is a square tube with aconstant wall thickness of 3 mm. The outerdimensions of the cross-sections are shown inthe figure. The tubesare attached to a rigid bracket at B, which isloaded by a couple formed by the forces P =16 kN. Determine the maximum shear stressin the shaft. Take G = 75 GPa.1.2m100 mm1.2m1 = 3 mm1= 2 mmImportant reminder: The formulas derived forthin-walled tubes are just approximations. So,for the case of hollow circular tubes withconstant thickness, you should still use Tc/Jand TL/JG to solve for the shear stress andangle of twist, respectively.

Soil engineering for highway design

Soil engineering is a part of geotechnical engineering that deals with the characteristics of soil. It also helps to understand the behavior of the soil in different conditions. The basic concepts of soil are studied to check the strength, compressibility, and porosity of the soil. This makes soil engineering an important topic for civil engineering.

Question

Q.4.1.L

The segment AB of the steel torsion bar is a
cylindrical tube of constant 2-mm wall
thickness. Segment BC is a square tube with a
constant wall thickness of 3 mm. The outer
dimensions of the cross-sections are shown in
the figure. The tubes
are attached to a rigid bracket at B, which is
loaded by a couple formed by the forces P =
16 kN. Determine the maximum shear stress
in the shaft. Take G = 75 GPa.
1.2m
100 mm
1.2m
1 = 3 mm
1= 2 mm
Important reminder: The formulas derived for
thin-walled tubes are just approximations. So,
for the case of hollow circular tubes with
constant thickness, you should still use Tc/J
and TL/JG to solve for the shear stress and
angle of twist, respectively.
