Question

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? (report result to 1 decimal place).

Answer #1

A simply supported basswood beam is designed to carry a
concentrated load P of 1100 lbf in the center. The
distance L between supports is 70 inches. Basswood has the
following properties: Modulus of Elasticity = 1.46 x 106
psi; Density = 28 lbm/ft3. Beam dimensions
are: Web thickness tw = 1.5 in, flange thickness
tf = 2 in., web width bw = 4 in., flange
height h = 6.75 in, total beam length = 110 in. What is the...

A 356 x 171 US45 steel beam is simply supported at the ends of a
span of 5.5 m. The beam carries a safe inclusive UDL of 12kN/m and
a point load of 75 kN at mid-span. Calculate the maximum deflection
due to this load.
Let:
E = 205 000 N/mm2
I = 12070 cm4
deflection δPL = PL/48EI
deflection δudL = 5wL3/384EI

For a simply supported beam of length L and uniform
cross-section (constant E and I with usual notation) with a
concentrated load P perpendicular to the beam at mid span, use
first principles and method of integration discussed to obtain an
expression for the maximum deflection.
If the concentrated load is still perpendicular to the beam but
not at the mid span, very clearly and briefly explain how you would
determine the maximum deflection of the beam.

A simply supported rectangular concrete beam is 18 in. wide and
has an effective depth of 32 in. The beam supports a factored load
(wu) of 15 kips/ft. on a clear span of 22 ft. The given load
includes the weight of the beam. Use f'c = 4,000 psi. and fy =
60,000 psi.
Over what length of span are stirrups required?
Group of answer choices
8.35 ft.
9.18 ft.
10.26 ft.
Stirrups are not required for this beam.
None...

A simply supported beam spans 20 ft. and carries a uniformly
distributed load of 1 kip/ft,including the beam self-weight, and a
live load of 2.5kip/ft. Determine the minimum required plastic
section modulus and select the lightest-weight W-Shape to carry the
moment (A992 Steel). Use LRFD method.

A simply supported #1 DF-L (Douglas Fir-Larch) beam 10 foot in
length has a uniform load of 100#/ft. The beam is 2 x 12 in the
strong axis orientation, and is fully braced, the moisture content
is less than 19% and the max deflection is L/360. (include the
weight of the beam in your calculations)
