Reference ASTM D746 - 07. This applies to Brittleness testing of elastomers and plastics.
A material will be graded as brittle when it breaks with only a small amount of strain. Its brittleness is based on the amount of deformation used to break the material.
An alloy may fail an elongation test primarily due to its microstructure and mechanical properties, which can include factors such as brittleness, insufficient ductility, and the presence of defects or inclusions. Poor alloying elements distribution or improper heat treatment can also contribute to reduced elongation. Additionally, if the alloy has a high yield strength but low plasticity, it may fracture before exhibiting significant elongation. These characteristics ultimately determine how well the alloy can deform under tensile stress without breaking.
in this test their is a no load on dc shunt motor so it is an indirect test
A mock test does not carry marks. It prepares one to be ready for an actual test.

Brittleness isn't a material, it's a characteristics.
Brittleness means the property of snapping easily when a force is applied.
No, oxygen itself cannot exhibit brittleness because it is a gas at normal atmospheric conditions. Brittleness is a mechanical property exhibited by solid materials when subjected to certain stresses.
Yes, brittleness is an intensive property. It describes the tendency of a material to fracture or break without significant deformation under stress, and it does not depend on the amount of material present.
It shows the fracture toughness of materials. higher the brittleness lower the fracture toughness and also lower will be the impact value and vice verse.
Brittleness is not a characteristic of most metals. Metals are usually ductile and malleable, meaning they can be bent and shaped without breaking. However, some metals, such as cast iron, can exhibit brittleness under certain conditions.
Brittleness is considered a physical change. It is a change that can be felt, and interacting with it does nothing to change it into something else.
the hardness of iron decreases with increase in brittleness in general..however when the temp is increased, the elasticity increases and the brittleness reduces, it continues to show the increasing trend in hardness until a transition temperature, after which the hardness starts decreasing again.
Brittleness. Reason: Non-metallic solids are usually brittle.
The brittleness of carbon fiber can impact its performance in different applications. In some cases, high brittleness can make carbon fiber more prone to cracking or breaking under stress, reducing its durability. However, in other applications where stiffness and strength are more important than flexibility, the brittleness of carbon fiber can actually be an advantage, providing excellent structural support. Ultimately, the impact of carbon fiber brittleness on performance depends on the specific requirements of the application.
The word is "brittleness."
