Answer:
The original length of the specimen 
Explanation:
Original diameter 
= 30 mm
Final diameter 
= 30.04 mm
Change in diameter Δd = 0.04 mm
Final length 
= 105.20 mm
Elastic modulus E = 65.5 G pa = 65.5 × 
M pa
Shear modulus G = 25.4 G pa = 25.4 × M pa
We know that the relation between the shear modulus & elastic modulus is given by
This is the value of possion's ratio.
We know that the possion's ratio is given by
0.00476
Final length 
= 105.2 m
Original length
This is the original length of the specimen.
Answer: True
Explanation: Ceramics have the property that when the band gap present between the atoms are larger than the light energy then the tend to become opaque because the light scattering is caused . They also show the property of being translucent when there are chances of the light to get a path through the surface of ceramic so they get the light at some parts e.g.porcelain .Therefore the statement given is true that ceramics can be optically opaque or semi-transparent(translucent).
Answer:
Explanation:
a) On the verge of tipping over, reaction acts at the corner A
When slippage occurs,
Block moves w/ const. velocity equilibrium
Three-force member: reaction at A must pass through B
tan b/2h, h b/ 2 θ µ = = ∴= k k ( µ )
b) When slippage occurs,
Block moves w/ const. velocity equilibrium
Three-force member: reaction at C must pass through G
k tanθ µ =
tan x/ H/2 , x H/2
Answer:
The mechanical gauge would be the one for the job
