Atomic Structure And Bonding
Atomic Structure And Bonding Atomic Structure Atoms are composed of protons, neutrons, and electrons. Protons are positively charged, electrons carry a negative charge, and neutrons are uncharged. In a neutral atom, the nucleus of protons and neutrons is surrounded by electrons, the number of which is equal to the number of protons. This number is also the same as the … [Read more...] about Atomic Structure And Bonding
Tensile Properties – Materials
Tensile Properties - Materials Write a short note on tensile strength and compressive strength Answer: Tensile Strength: It is determined by subjecting a rod, wire, or dumbbell-shaped specimen to a tensile loading. Tensile strength is defined, as the maximal stress the structure will withstand before rupture. Due to tensile loading, there is an alteration in the … [Read more...] about Tensile Properties – Materials
Material Hardness – Types, Testing Methods And Units
Material Hardness – Types, Testing Methods And Units Write a short note on Hardness. Answer: Hardness is defined as resistance to permanent indentation. Initially, an arbitrary hardness indexing scheme known as the Mohs scale is used to determine hardness.
