Question

Transcribed Image Text:A cantilever beam AB, loaded by a uniform load and a concentrated load,
is constructed of a channel section. Find the magnitude of the maximum
compressive stress (MPa) due to bending if the cross-section has the
dimensions indicated and the moment of inertia about the z –
cm4. The uniform load represents the weight of the beam.
axis is 130
1 kN
320 N/m

Transcribed Image Text:A beam with a T-section is supported and loaded as shown in the figure.
The cross-section has width b
= 65 mm, height h = 75 mm, and thickness
t = 13 mm. Determine the magnitude of the maximum tensile stress
(MPa) in the beam due to bending.

1 = 13 mm
P = 4.5 kN
Lj = 1.25 m
q = 2 kN/m
1 = 13 mm
h = 75 I
L2 = 2.5 m - L3 = 1.5 m →
b = 65 mm
