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 cm. What will be the length and diameter of the
steel rod if the total
elongation of the steel rod was found to be 25% and the area of
contraction at fracture estimated
was 12%? Based on the test results, determine the values
for the stress corresponding to limit of
proportionality, modulus of elasticity of the material and the
ultimate stress developed due to
tension.

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 .

. 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...

When the rod shearing process at Newcastle Steel is ‘in control’
it produces rods with a mean length of 120 cm. Periodically,
quality control inspectors select a random sample of 36 rods. If
the mean length of sampled rods is too long or too short, the
shearing process is shut down. The last sample showed a mean of
120.3 cm with a standard deviation of 0.9 cm. Using α = 0.05, the
appropriate decision is _________.
do not reject the...

A model of a Francis turbine is built to a scale of one fifth of full size and when tested it developed a power output of $3 \mathrm{~kW}$ under a head of $1.8 \mathrm{~m}$ of water, at a rotational speed of $360 \mathrm{rev} / \mathrm{min}$ and a flow rate of $0.215 \mathrm{~m}^3 / \mathrm{s}$.Estimate the speed, flow rate, and power of the full-scale turbine when working under dynamically similar conditions with a head of $60 \mathrm{~m}$ of water. By making...
