- The road is the dominant mode in relation to external
Materials Science and Engineering
Material Properties
Elasticity
Capacity of materials to return to their original form after the force is removed.
Plasticity
Material’s ability to retain its shape once deformed.
Ductility
Ability to stretch the material into wires.
Malleability
Material’s ability to stretch without breaking.
Hardness
Opposition of a material to be penetrated by another material.
Fragility
The material breaks into splinters when impacted by a force.
Toughness
Resistance opposed by a body when subjected to deformation efforts.

Ans:Read More
The B-tree was invented in 1972 by R. Bayer and E. McCreight, and was designed from the start to create shallow trees for fast disk access. Shallow trees have few �levels�, We have to seek through them fewer times, and therefore they run quickly. Because seeks often require going to disk for the information we need, The performance increase with a shallow tree rather than a deeper
Hydraulic Systems Components and Operation
1) Basic Components of a Pond and Their Functions
1. Vent: Since the oil inside the tank comes and goes, you need a vent to allow air to enter or exit when the oil level changes, preventing a vacuum.
2. Oil Level: The level indicator is used to verify the current oil volume in the tank, which should ideally be twice the amount used by the circuit.
3. Thermometer: This checks the oil temperature in the reservoir, as each type of oil has specific operating temperature limits.
4. Oil Output: This is where

Metal Casting
Casting of Metals
Iron, known for its hardness and elasticity, cannot be worked directly (it requires rolling and merging). Various techniques are employed to create sculptures, including building (shaping iron with fire and a hammer). Two primary methods exist:
- Direct (forging, spinning): Striking hot or cold rods.
- Casting: Notably, the Lost Wax Technique.
Welding
Welding involves melting using an iron electrode on both surfaces, resulting in a strong and rigid union. Welding by contribution
