Q1 / An axial load of 75 kN was applied to a steel rod
of 3 m in length and 0.025 m in diameter. Calculate the change in
length (∆L), Poisson’s ratio, percent elongation and percent
reduction in
area. Take change in diameter (∆d) = 5.73 x10 mm and E = 200 kN /
mm .

An axial pull of 45 kN is applied on the three bars of
varying cross section and connected to
each other as shown in figure. Two outer steel bars are of same
length and diameter, but the
middle bar made up of brass having cross sectional dimensions 20 mm
x 20 mm. The length of the
middle bar used was 4 times more than that of the two outer bars
and stress in the two outer
portion were found to...

A short reinforced concrete column is subjected to a
1000 kN axial compressive load. The moduli of elasticity of plain
concrete and steel are 25 GPa and 207 GPa, respectively, and the
cross-sectional area of steel is 2% of that of the reinforced
concrete. Considering the column as a structural member made of a
composite material and subjected to load parallel to the steel
rebars, calculate the following:

In a sample of 75 steel wires, the average breaking strength is
50 kN, with a standard deviation of 1.9 kN. a) Find a 99%
confidence interval for the mean breaking strength of this type of
wire. b) An engineer claims that the mean breaking strength is
between 49.7 kN and 50.3 kN With what level of confidence can this
statement be made? c) How many wires must be sampled so that a 99%
confidence interval specifies the mean breaking...

A 300 kN point load is applied to a soil profile that consists
of 7 meters of sand (γt = 19 kN/m3) above 4 meters of clay (γt =
17.5kN/m3) with the groundwater table at a depth of 5 meters. The
clay has an OCR = 1.6, an initial void ratio of 0.86, a Cc=0.64 and
a Cr=0.12. The sand has a Cc = 0.35 and an initial void ratio of
0.68. Calculate the overall settlement of the profile due...

. A rectangular steel bar is subjected to a fluctuating load
from 30 kN tension to 30 kN compression. The bar is 30 mm wide and
7 mm thick with a hole in the middle that is 4 mm in diameter. Find
the fatigue and yield factor of safety if the steel is cold-drawn
AISI 1040. If the fatigue factor nf<1 and ny>1 then that
means that the system will fail at a finite number of cycles. If
that is...

Q3: When a mild steel rod was tested under tension, it
was observed that a load of 8 kN causes an
extension of 0.024 cm in the rod. The maximum load carried by the
steel rod was observed to be
20 kN and the load beyond which stress is not proportional to
strain was noted as 10 kN. When the
specimen breaks, the elongation in the rod measured was 5.25 cm and
the diameter at the fracture
observed was 0.455...
