A beam is subjected to equal bending moments of Mz = 44 kip·ft.  The cross-sectional dimensions are b1 = 6.5 in., d1 = 1.0 in., b2 = 0.95 in., d2 = 5.0 in., b3 = 2.0 in., and d3 = 1.5 in.  Determine: (a) the centroid location (measured with respect to the bottom of the cross-section), the moment of inertia about the z axis, and the controlling section modulus about the z axis. (b) the bending stress at point H. Tensile stress is positive, while compressive stress is negative. (c) the bending stress at point K. Tensile stress is positive, while compressive stress is negative. (d) the maximum bending stress produced in the cross section. Tensile stress is positive, while compressive stress is negative.
A beam is subjected to equal bending moments
of M₂ = 44 kip.ft. The cross-sectional
dimensions are b₁ = 6.5 in., d₁ = 1.0 in., b₂ = 0.95
in., d₂ = 5.0 in., b3 = 2.0 in., and d3 = 1.5 in.
Determine:
(a) the centroid location (measured with
respect to the bottom of the cross-section), the
moment of inertia about the z axis, and the
controlling section modulus about the z axis.
(b) the bending stress at point H. Tensile stress
is positive, while compressive stress is negative.
(c) the bending stress at point K. Tensile stress
is positive, while compressive stress is negative.
(d) the maximum bending stress produced in
the cross section. Tensile stress is positive,
while compressive stress is negative.
