. In what way the deflection affects the strength and stability
of the steel structure?. Elaborate the limit states that controls
the deflection. As a civil engineer specify the standard codal
provision for deflection limits?
After full analysis of a solid steel shaft considering
deflection, strength and vibrations, we come to know that the shaft
design is limited by deflection, which option as a designer would
you pursue, provide reasoningfor your choice.
(a)Increase the shaft diameter but make the shaft hollow while
keeping the weight constant
(b)Keep the shaft diameter constant and select a shaft with
higher strength
(c)Increase the shaft diameter to increase the critical speed
and select a steel with higher strength
(d)Increase...
1 A steel helical spring carries a
compressive load of 32.4 pounds at a deflection of 0.25 inches.
Maximum stress is 73240psi. The spring has 1.5 end turns. Calculate
the value of c for the spring of minimum volume material.
Calculate the value of d and choose the nearest standard
wire diameter for the actual spring. Calculate the corresponding
R and the number of active coils Nc.
Also, calculate the material in the spring.
An engineer who is studying the tensile strength of a steel
alloy knows that tensile strength is approximately normally
distributed with sigma= 60 psi. A random sample of 12 specimens has
a mean tensile strength of 3450 psi.
a) Compute a two-side confidence interval on the maen tensile
strength at a 95% confidence level.
b) Test the hypothesis that the mean strength is 3500 psi at
alfa=0.05, and provide a conclusion statement.
c) If we keep the signifiance level constant...

body
An ASTM A36 steel having a yield strength of 235 MPa, a tensile
strength of 640 MPa, and an endurance limit of 210 MPa is subjected
to a cyclic loading. Using the Goodman diagram, predict whether the
material has an infinite fatigue life, or whether it will fail by
yielding or fatigue, when the cyclic stress is between:
(i) 0 and 250 MPa.
(ii) 95 ± 220 MPa
Though steel have high tensile strength, detailing is necessary
not only for the steel structures but also for the RCC members as
it is the translation of all the mathematical expression’s result.
For that matter, coin a comprehensive definition for detailing of
reinforcement bar (steel).
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...
