Question

A
polymer rod of ten millimeter in diameter and forty millimeter in
length is elongated by applying a force of four thousand newton.
Polymer rod has a Poisson's ratio of 0.50 and a longitudinal strain
of 2.5 x 10−2 Calculate: (A) the polymer rod extension,(B) the
change in radius of the polymer rod and (C) percentage change in
its volume.

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...

A rod has a square cross section of (5 x 5) mm. length of the
rod is 120 cm. The allowable stress is 400 MPa. After applying the
load (F), square section changes to (4.95 x 4.95) mm.
1. What is the type of the load (F), is it tension or
compression?
2. What is the longitudinal strain in steel rod?
3. What is the modulus of elasticity of the material of the
rod?
4. What is the value of...

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...

What is the change in length of a metal rod with an original
