7.8 The following figure shows an L-shaped bracket made of structural steel
with Young’s modulus E = 200 GPa and Poisson’s ratio ν = 0.3. The 4 cm thick
L-shape with a cross-section profile shown in the figure is rigidly connected to
a rectangular base of size 3 cm × 8 cm × 1 cm. Suppose that the bracket is fixed
on the right end at the base. A uniform pressure of 100 N/cm is applied on the
2
protruding surface of the L-shape as shown below. Compute the deformation
and stresses in the bracket using the FEA.

All dimensions are in
centimeters.

7.9 The following two-bar assembly consists of four components made of struc-
tural steel with Young’s modulus E = 200 GPa, Poisson’s ratio ν = 0.3, and den-
sity ρ = 7850 kg/m . As shown in the figure below, the two bars are identical in
3
size. Each bar has a diameter of 2 cm and a length of 16 cm. The two identical
end blocks each has a thickness of 2 cm and a fillet radius of 1 cm at the round
corners. The distance of the gap in between the two blocks is 8 cm. Suppose that
the two blocks are fixed on the bottom. The bars are pulled by a pressure load of
100 N/cm in opposite directions as shown below. Compute the stresses in the
2
assembly using the FEA.
