A cylinder of an unknown length made of copper is used being used to support a roof is deformed elastically in tension by a force. The diameter of the cylinder is 25 mm. The reduction in diameter is 3*10^-3 mm Given the following information, what is the Stress experienced by the cylinder?
modulus of elasticity for copper:110 GPA
Poissons ratio for copper:0.34
Solutions
Expert Solution
Given, The diameter of the cylinder is, d =
25mm
The reduction in diameter is, 
=
Modulus
of elasticity for copper is,E = 110 GPa
Poissons ratio for copper,
= 0.34
We Know, Modulus of rigidity, 
where, E is modulus of elasticity
is poissons ratio
Also, Modulus of rigidity,
Answer,Stress acting on the cylinder

The circular fin of diameter D=1mm and length L=25.4mm, made of
copper (k=400 W/m.K), are used to enhance heat transfer from a
surface that is maintained at temperature Tb=132 °C. and the rod
has another end attached to a large surface which is maintained at
Te= 0°C. The airflow through the rod surfaces is at T∞ = 0 °C with
convection heat transfer coefficient h = 100 W/m2.K. (Hint: use
table 3.4 in the lecture slides.)

1. A cube
(length of each side: 10 cm), made from some unknown material,
floats on the surface of the ocean. If 72% of the total volume of
this cube is underwater, determine: a) the total mass of water
displaced by the cube b) the buoyant force acting on the cube c)
the total mass of the object d) the density of the

Find the length and width of the parabolic cylinder.
Let's suppose that you want to cook 1 lb of hot dogs
using a parabolic trough concentrator on a clear June day in Los
Angeles. The hot dogs would be skewered on a stiff piece of wire
and aligned along the axis of the trough in the same position in
which the absorber/receiver normally would be placed. The desired
cooking time is 10 mins, with the resulting surface temperature of
the hot dog about 450 F.Find the length and width...

A narrow copper wire of length L and radius b is attached to a
wide copper wire of length L and radius 2b, forming one long wire
of length 2L. This long wire is attached to a battery, and a
current is flowing through it. If the electric field in the narrow
wire is E, the electric firld in the wide wire is.

a sample of unknown liquid is weighed in a graduated cylinder
and the mass is 240.56 g. The empty graduated cylinder weighs
172.21 g. The volume of the liquid is 38.54 mL. What is the density
of the liquid?

Suppose you made a copper-nickel cell where the copper was the
cathode and the nickel was the anode. You add a 0.5000 M solution
of copper nitrate on the cathode side and a 3.000 M solution of
nickel nitrate on the anode side. What is the voltage of the cell
under these conditions? The units are volts and use at least 4
significant digits in the answer. The error interval is 0.02 V.

There is uniformly charged hollow cylinder The cylinder has
radius R, length L, and total charge Q. It is centered on the
z-axis, with one end at z=−L/2 and the other at z=+L/2.We are
interested in finding the electric field generated by the cylinder
at a point P located on the z-axis at z=z0.
-Consider a thin ring segment of the cylinder, located at height
z and having thickness dz. Enter an expression for the charge dQ of
the ring?...
