Internal forces and stress
The crane boom is subjected to the load of 500 lb. Determine the
normal stress at points A and B.
Note: one of the answers below is compressive, you must identify
which one.
Ans. σΑ=10.1ksi
σΒ=10.3ksi
The crane boom is subjected to the load of 500 lb.
a) determine the internal forces acting upon the AB section, b) make a sketch showing the stress
distribution of every internal force acting upon this
cross section. b) determine the normal stress at
points A and B produced by the 500 lb load;
Unsymmetric bending case. The 5 ft column
supports the 400 lb load acting on the x-z
plane. Determine the normal stresses
generated at the corners A, B, C, and D of the
shape, for a cross section located at the fixed
end.

Caso de elementos curvos
A 5klb load is applied to a shaft which is 8 in
long and has a diameter of 2 in. Determine the
state of stress for each point, A and B, located at
the fixed end over the quadrant of the cross
sectional area as shown.
