Answer:
C. Provides lubrication to parts
Explanation:
Flywheel :
Flywheel is a device which stored the mechanical energy.This energy can be use when more energy required during any operation.Due to high moment of inertia of the flywheel it resist the change in the speed .The flywheel is attached to the crank shaft at the rear side of the engine.
The flywheel perform following function:
1. It connects the crankshaft and the transmission system.
2.It makes the engine operation smooth.
3.It contains gear and other parts of the engine.
But it can not provide lubrication.
C. Provides lubrication to parts
Answer:
The required wall thickness is 
m
Explanation:
Given:
Fluid density 
Diameter of tank 
m
Length of tank 
m
F.S = 4
For A-36 steel yield stress 
MPa,
Allowable stress 
MPa
Pressure force is given by,
Pa
Now for a vertical pipe,
Where 
required thickness
m
Therefore, the required wall thickness is m
Answer:
What is the difference Plastic vs elastic deformation
Explanation:
The elastic deformation occurs when a low stress is apply over a metal or metal structure, in this process, the stress' deformation is temporary and it's recover after the stress is removed. In other words, this DOES NOT affects the atoms separation.
The plastic deformation occurs when the stress apply over the metal or metal structure is sufficient to deform the atomic structure making the atoms split, this is a crystal separation on a limited amount of atoms' bonds.

Answer:
13.95
Explanation:
Given :
Vector A polar coordinates = ( 7, 70° )
Vector B polar coordinates = ( 4, 130° )
To find A . B we will
A ( r , ∅ ) = ( 7, 70 )
A = rcos∅ + rsin∅
therefore ; A = 2.394i + 6.57j
B ( r , ∅ ) = ( 4, 130° )
B = rcos∅ + rsin∅
therefore ; B = -2.57i + 3.06j
Hence ; A .B
( 2.394 i + 6.57j ) . ( -2.57 + 3.06j ) = 13.95
