Explain the behavior of rc beam (load-deflection or
Moment-curvature) under the flexural loading highlighting different
stages of loading till failure; i.e. un-cracked section, cracked
section, service condition, yielding and ultimate loading
condition.
A rectangular beam carrying a uniform load of 26 KN/m including
its own weight is limited in cross section to 300 mm x 500 mm. The
beam is simply supported in a span of 6 m. Using fc = 7 Mpa, fs =
124 Mpa, n = 12, ?? = 40 ???, ?? = 1.7 ???, ?????? ?ℎ? ????. Allow
65 mm distance from centroid of steel bars to extreme fibers.
2. Design an all-bolted double-angle connection for a W24x146
A992 beam to carry a dead load reaction of 25 kips and a live load
reaction of 75 kips. Use 5/16 in. angles and ¾ in A325N bolts in
standard holes. The uncoped beam is connected to the flange of a
W14x132 column. Design by both LRFD and ASD method.
in table 1 the failure load obtained from the compressive
strength test at the laboratory are presented. sate

The excess temperature
θ of a motor under load over that
of its surroundings at time t is given by ( dθ
/ dt = 10 -
kθ, ) where k is
constant. if
θ=50 when t=10, find
θ at any other time.
Two beams of electrons, beam 1 and beam 2, are moving along
straight lines perpendicular to the page. We take the page to be
the xy-plane. Beam 1 is moving into the page and intersects the
page at point (−2, cm, 0 cm). Beam 2 is moving out of the page and
intersects the page at point (2, cm, 0 cm). The streams of
electrons are otherwise identical, each carrying current of
magnitude 2 A. A negatively-charged particle having charge...
A beam of spin‐1/2 particles is prepared in the state:
20 2 20 4 i a) What are the possible results of a measurement of
the spin component Sz and with what probabilities would they occur?
b) What are the possible results of a measurement of the spin
component SX and with what probabilities would they occur? c)
Suppose that the SZ measurement yields the result SZ = ‐ħ/2.
Subsequent to that result a second...
The
three Primary failure modes for concrete dams are:
1-Stability under acting loads
2-Load-bearing capacity (due to e.g. degradation or
cracks)
3-Water-tightness
Describe these-give the reason for when and how each of them
Will occur?
2.) The tensile strength of a metal is a measure of its ability
to resist tearing when it is pulled lengthwise. To see if a new
experimental method of treating steel bars improves tensile
strength, random samples of bars treated using the experimental
method and treated using the old method are taken and the tensile
strengths are measured and recorded (in newtons per square
millimeter). Assume both populations are approximately normally
distributed.
Experimental Method: 362 382 368 398 381 391...
