definition of ceramics
Answer:
Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven known as a kiln. Often, ceramics are covered in decorative, waterproof, paint-like substances known as glazes.
Explanation:
Answer:
made essentially from a nonmetallic mineral (such as clay) by firing at a high temperature.

53. The plan of a building is in the form of a rectangle with
centerline dimension of outer walls as 9.7mx14.7m. The
thickness of the wall in super structure is 0.30m. Then its
plinth area is
a) 150m
b) 145m2
c) 145.5m
d) 135.36m
.
Answer: 150m
Explanation:
The following can be depicted from the question:
Dimensions of outer walls = 9.7m × 14.7m.
Thickness of the wall = 0.30 m
Therefore, the plinth area of the building will be:
= (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)
= 10 × 15
= 150m
The plinth area will be 150m.
Given information
Dimensions of outer walls = 9.7m × 14.7m.
Thickness of the wall = 0.30 m
Plinth area of the building = (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)
Plinth area of the building = 10 × 15
Plinth area of the building = 150m
Therefore, the Option A is correct.

The coolant heat storage system:
Select one:
A. increases hydrocarbon exhaust emissions,
B. uses a condenser.
C. preheats the engine when the vehicle is started the next time.
D. prevents the engine from overheating on hot days.
Answer:
c
Explanation:
This is because many things, such as pcs, over heat
Preheats the engine when the vehicle is started the next time. Therefore, the correct answer is option C.
The coolant heat storage system is designed to store heat from the exhaust system when the vehicle is operating and then use that heat when it is started again. This gives the car a kind of "head start" and the engine does not need to work as hard to heat up and become ready for driving. This can save on fuel consumption and hydrocarbon emissions. This process is done with the use of a condenser to store the heat energy. Additionally, the coolant heat storage system can also help to prevent the engine from overheating in hot weather and conditions.
Therefore, the correct answer is option C.

The question is incomplete. The complete question is :
The hydrofoil boat has an A-36 steel propeller shaft that is 100 ft long. It is connected to an in-line diesel engine that delivers a maximum power of 2590 hp and causes the shaft to rotate at 1700 rpm . If the outer diameter of the shaft is 8 in. and the wall thickness is [tex]$\frac{3}{8}$[/tex] in.
A) Determine the maximum shear stress developed in the shaft.
[tex]$\tau_{max}$[/tex] = ?
B) Also, what is the "wind up," or angle of twist in the shaft at full power?
[tex]$ \phi $[/tex] = ?
Solution :
Given :
Angular speed, ω = 1700 rpm
[tex]$ = 1700 \frac{\text{rev}}{\text{min}}\left(\frac{2 \pi \text{ rad}}{\text{rev}}\right) \frac{1 \text{ min}}{60 \ \text{s}}$[/tex]
[tex]$= 56.67 \pi \text{ rad/s}$[/tex]
Power [tex]$= 2590 \text{ hp} \left( \frac{550 \text{ ft. lb/s}}{1 \text{ hp}}\right)$[/tex]
= 1424500 ft. lb/s
Torque, [tex]$T = \frac{P}{\omega}$[/tex]
[tex]$=\frac{1424500}{56.67 \pi}$[/tex]
= 8001.27 lb.ft
A). Therefore, maximum shear stress is given by :
Applying the torsion formula
[tex]$\tau_{max} = \frac{T_c}{J}$[/tex]
[tex]$=\frac{8001.27 \times 12 \times 4}{\frac{\pi}{2}\left(4^2 - 3.625^4 \right)}$[/tex]
= 2.93 ksi
B). Angle of twist :
[tex]$\phi = \frac{TL}{JG}$[/tex]
[tex]$=\frac{8001.27 \times 12 \times 100 \times 12}{\frac{\pi}{2}\left(4^4 - 3.625^4\right) \times 11 \times 10^3}$[/tex]
