During construction, field tests were conducted to assess the
suitability of the column to
withstand a safe buckling load of 2.5 kN assuming a factor of
safety 4 using two different hollow
columns made up of steel and concrete. Both columns have same cross
section but varying length
and different support conditions. Steel column of length 3 m having
external diameter 40 mm was
tested with one end fixed and the other end hinged, when subjected
to a compressive stress of
0.0045 MN/cm2 shortens by 3.6 mm.
If the concrete column was tested under similar loading conditions
with one end fixed and other
end free considering modulus of elasticity of concrete equal to 128
GPa, what will be the
corresponding length of the column required? As a design engineer
how do you choose the values
for the thickness of both columns and the length of the concrete
column? What will be your
interpretations regarding the relationship between the support
conditions and the buckling load
based on the test results?

A) A study is conducted to assess the relationship between the
use of marijuana during pregnancy and adverse delivery outcomes,
defined as major congenital malformations. The following variables
are used in the analysis.
Delivery outcome: major congenital malformation versus other
delivery.
Risk factors:
1. Marijuana usage during pregnancy: yes or no
2. Race: White or non-white
3. SES categorized as: low, middle, or high
4. Maternal age
5. Any previous stillbirth: yes or no

Deflection tests were conducted on a steel joist and a
timber joist both simply supported over a span of 5 m and carrying
a point load of 45 kN at distance of ‘a’ from left support. Maximum
deflection was observed at a position 2.4 m from the left support
for steel joist and 1.85 m from the left support for steel joist.
Calculate and compare the results for maximum deflection, slope at
both ends and deflection under the load for...

Medical tests were conducted to learn about drug-resistant
tuberculosis. Of 142 cases tested in New Jersey, 9 were found to be
drug-resistant. Of 268 cases tested in Texas, 5 were found to be
drug-resistant. Do these data suggest a statistically significant
difference between the proportions of drug-resistant cases in the
two states? Use a .02 level of significance. What is the
p-value, and what is your conclusion?

During the construction phase of a health-care project, delays
not attributed to the
contractor were experienced, but the contractor was delayed in
submitting all delay
information required by the contract until 7 days before the
contractual completion date,
can the architect issue an extension of time prior to the
completion date? Explain.
