Question

A simply supported basswood beam is designed to carry a
concentrated load P of 1100 lb_{f} in the center. The
distance L between supports is 70 inches. Basswood has the
following properties: Modulus of Elasticity = 1.46 x 10^{6}
psi; Density = 28 lb_{m}/ft^{3}. Beam dimensions
are: Web thickness t_{w} = 1.5 in, flange thickness
t_{f} = 2 in., web width b_{w} = 4 in., flange
height h = 6.75 in, total beam length = 110 in. What is the
deflection of the beam (in inches) at the mid-point (center) of the
span if designing to include a safety factor of 1.75? (Report
result to 3 decimal places)

Answer #1

a simply supported beam having a span length equivalent to
2008(mm). the beam is carrying uniform distributed load having
intensity of 08(N/mm) that span from the origin to two third of the
entire span, together with concentrated load of 50N at the mid=span
of the beam.
the beam cross-section details are;
-beam type = inverted tee flange beam
- flange lenght = 008mm
flange thickness= 20mm
web height = 171mm
web thickness= 20mm
Answer the following question
a) sketch the...

simply supported timber beam is 14 feet long with
cross-sectional dimensions of 4 in. wide by 10 in. tall. The beam
is supported at its ends and carries a concentrated load of 5 kips
at its center. The modulus of elasticity is 1.7×106
psi.
The deflection at the center is most nearly

A simply Supported Steel "I Beam" is made of three 1" x 7"
plates with a mass of 898.4 lbm each as shown below. Steel has a
modulus of elasticity of 30x10^6 psi. The beam is allowed to
deflect 1.10 in. The length of the beam L between supports is 10.5
feet.
a) If i turn the same beam clowise 90 degrees, what percentage
of the problem 20 maximum load can i apply to yield the same 1.10
inch deflection?...
