What is a Charpy Impact Test? - TWI

What is a Charpy Impact Test? The Charpy impact test, also known as the Charpy V-notch test, is a high strain-rate test that involves striking a standard notched specimen with a controlled weight pendulum swung from a set height. The impact test helps measure the amount of energy absorbed by the specimen during fracture.

Machining 101: What is Five-Axis Machining? | Modern ...

Five-axis machining adds rotational movement to the traditional three axes of linear motion (X, Y and Z). These machines can incorporate an A-axis that handles rotation of the X-axis, a B-axis that does the same for the Y-axis, or a C-axis that rotates about the Z-axis. Some employ rotary, tilting tables, which provide mechanical and thermal ...

Bessemer Process - an overview | ScienceDirect Topics

The bessemer process reduces molten pig iron in so-called bessemer converters—egg-shaped, silica, clay, or dolomite-lined containers with capacities of 5 to 30 tons of molten iron. An opening at the narrow upper portion of the bessemer converter allows iron to be introduced and the finished product to be poured out. Melting of metal typically is accomplished with coal and …

What is Motion and Types of Motion - A Plus Topper

A type of motion that repeats itself after equal intervals of time is called periodic motion. Examples of objects undergoing periodic motion are the to and fro motion of a pendulum, the Earth (rotating on its axis), the hands of a clock, the blades of a rotating electric fan, and the plucked string of a guitar.
