Answer:
Plastic deformation, irreversible or permanent. Deformation mode in which the material does not return to its original shape after removing the applied load. This happens because, in plastic deformation, the material undergoes irreversible thermodynamic changes by acquiring greater elastic potential energy.
Elastic deformation, reversible or non-permanent. the body regains its original shape by removing the force that causes the deformation. In this type of deformation, the solid, by varying its tension state and increasing its internal energy in the form of elastic potential energy, only goes through reversible thermodynamic changes.
Answer:
Option B
Explanation:
A logistician mainly manage the purchasing, transportation, inventory, and warehousing. He/She guide the movement of goods and people from th production plant to the warehouse and then to the consumer. He/She uses software to plan and track the movement of goods/products.
Hence, option B is correct

Answer:
Plain Bearings and Rolling Element Bearings -
Explanation:
two different type of bearing are:
1) Plain Bearings - Plain bearings are the easiest form of bearings and consist of only the layer of the bearings without rolling components.
2)Rolling Element Bearings - Rolling element bearings use balls or rollers between two rings – allowing movement with little rotating and sliding friction. These type of bearings include bearings for balls and rollers.
Answer:
14.27 mm
Explanation:
Force = 80 Newton
Pressure exerted = 5 bar = 5×10⁵ Pa
Pressure exerted = Force/Area
Area = Force/Pressure
Area of the cylinder=πd²/4
Hence diameter of cylinder 14.27 mm
