Find the yongs modulus (E) of a brass rod of diameter 28mm and length 250mm which subjected to a tensile load of 50KN and cause extension of the rod is equal to 0.3mm

Answer #1

Q3: Tension test was conducted on a mild steel rod having
diameter 1.5 cm and length 20 cm. While applying a load of 10 kN,
there will be an extension of 0.012 cm on a length of 20 cm.
Maximum load carried by the rod was found to be 26 kN and the load
beyond which stress is not proportional to strain was observed to
be 11 kN. When the specimen breaks, the extension of the rod for 20
cm...

When a square yellow cast brass rod is subjected to tensile
load, it should not extend more than 2.5mm. Since E = 105GPa and
the material safe
strength value σ = 180MPa; Determine
(a) the maximum allowable length of the rod,
(b)If the tensile load is 40N, determine the size and dimensions of
the cross section.

removed?

Find the axial displacement of a rod given properties
L(length), A (cross sectional area), E (Modulus) impacted axially
by a mass m moving with a velocity v0?

A copper rod, an aluminum rod, and a brass rod, each of 6.00 m
length and 1.00 cm diameter, are placed end to end with the
aluminum rod between the other two. The free end of the copper rod
is maintained at water’s boiling point, and the free end of the
brass rod is maintained at water’s freezing point. We know that
??????? = 401 W⁄m. K , ????????? = 235 W⁄m. K and ?????? = 109 W⁄m.
k. What...

In a bar drawing manufacturing process a2.0” long rod with a
diameter of 0.5” is pulled with a F=6000 lb. force.The diameter
decreases permanently to 0.4”.
Determine:
a.The final length of the rod
b.The true stress and strain at this load.
c. The engineering stress and strain at this load.
d. The stress at which necking occurs.
e. If the length just before necking occurs is 4.0 “ , find the
force at which necking occurs.
Strength coefficient k= 100...

Due to the operational conditions and temperature gradient, a 70
mm diameter, 1.55 m long
steel rod within a machine assembly is subjected to a combination
of tensile loading of 150 N and
thermal loading which imposes a longitudinal force of 230 N. The
total loading results in an even
distribution of forces on the body of the rod causing it to change
its dimensions by increasing 0.5
mm in length at both ends and decreasing by 0.0125 mm at...

The elastic modulus, yield strength and ultimate strength of a
certain material
are 110 GPa, 240 MPa and 265 MPa, respectively. If a cylindrical
bar of this
material 380 mm long is subjected to a uniaxial tension test and
its length is
increased by an amount of 0.50 mm under a tensile load of 6660 N.
At the same
time its diameter decreased by 0.28 mm. Calculate;
a) The initial diameter of the bar,

a.) An aluminum rod has an initial length of Lo = 670
[mm] and has an initial temperature of 24.5o. At what
value should the temperature be raised such that the rod would
expand at a length of 672.01[mm]? The coefficient of thermal
expansion of aluminum is 23.80x10^-6 Co.
b.) Three rods made of copper, aluminum, and brass has the same
initial length Lo. All rods expand to the same final
length L when subjected to change temperature. Which of...
