A rectangular glass plate (Young's Modulus 70 GPa, Ultimate
Tensile Strength 138 MPa, fracture Toughness Kic = 1.2 MPa.m0.5)
has a length of 200 mm, width of 100 mm and a thickness of 5 mm.
The plate is subjected to an in-plane tensile load across its
width.
(a) What is the maximum load the plate can carry ifit had no
flaws?
(b) What is the maximum flaw size that can be tolerated at the
centre of the plate before the...

For a brass alloy, the tensile strength is 400 MPa, the yield
strength is 315 MPa and the modulus of elasticity is 100 GPa.
(a) What is the maximum load that may applied to the specimen
with a cross sectional area of 130 mm2 before it fractures?
(b) For the same cross sectional area, if the original length of
the specimen is 75 mm what will be the length of the specimen, when
a load of 13000 N is applied...
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
When subjected to a force of compression, the length of a bone
(compression Young's modulus 9.4 x 109 N/m2,
tensile Young's modulus 1.6 x 1010 N/m2)
decreases by 2.7 x 10-5 m. When this same bone is
subjected to a tensile force of the same magnitude, by how much
does it stretch?Type your question here

Tensile tests of a 3D printed material show that the average
yield strength of that material is about 800 MPa with a standard
deviation of 40 MPa. Due to the variations of the process
parameters, the yield strength can vary, and historical data show
that yield strength of the material follows a uniform continuous
distribution. Answer questions 1a to 1e using this information.
1.If yield strength of the material is uniformly distributed
between 730.72 to 869.28, what is the expected...
Yield strength and modulus of elasticity of steel containing
0.4% carbon had been determined as 300 MPa and 230 GPa,
respectively. Estimate the yield strength and modulus of elasticity
of the steel for a carbon content of 1.1% and explain the way of
your estimation.
