Question

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 1.7×10^{6}
psi.

The deflection at the center is most nearly

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...

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 30 ft. and carries a uniformly
distributed dead load of 3.5 kip/ft,excluding the beam self-weight.
Also, in addition, a concentrated dead load of 15 kips and a
concentrated live load of 25kips, both act at the center of a 30 ft
span.Select the lightest-weight W-Shape to carry the load(A992
steel). Use LRFD method.

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?...

For a 8m long column whose cross sectional dimensions are 0.1m x
0.4m, determine the allowable load using a safety factor of 2.5.
The column is welded at both ends. Its yield stress is 250 MPa and
its modulus of elasticity is 210 GPa. using Euler Formula or J. B.
Johnson Formula.

A simply supported beam is 3 m long. It carries a uniformly
distributed load of 6 kN/m throughout its span and a concentrated
load of 15 kN at a point 2 m from the left support. Assuming that
the beam has a rectangular shape whose width and depth are 150 mm
and 250 mm, respectively. Determine the maximum flexural stress in
MPa developed in the beam.

A 1200 mm deep by 750 mm wide post-tensioned simply supported
beam is shown below. The beam spans 12.0 m and is subject to a
superimposed dead load of 50 kN/m and a live load of 35 kN/m. Both
the superimposed dead load and live load are applied after transfer
(after stressing has taken place). The tendon is located at the
mid-height of the beam at each end, and its centreline sits 50 mm
from the base at midspan. The...
