Answer:

(B) dimensions, tolerances, materials, and finishes of a component.

Explanation:

An engineering drawing :

  An  engineering drawing is a technical drawing which draws the actual component .

An engineering drawing shows

1. Materials

2.Dimensions

3.Tolerance

4.Finishes of a component

Engineering drawing does not shows any information about the cost of component.

So the option B is correct.

Write down the types and tasks of the pressure control valves ?
Yuki888 [10]

Answer:

There are 6 types of pressure control valves and their function is to regulate the pressure below a threshold level within safe limits and to maintain and control  pressure of a particular circuit.

Explanation:

The six type of Pressure valve with their functions are given below:

a. Unloading Valve:

These type of pressure valve are used to pour fluid into the container at very low or no pressure.

b. Safety valve:

These are used when the pressure within the vessel is in excess as inside temperature is near about preset [point point then these valves are open to release the extra pressure and are closed once normal conditions are regained.

c. Pressure Reducing Valve:

These are basically used for the control of the pressure in downstream not exceeding the design limits.

d. Pressure Relief Valves:

These are basically used to limit and regulate the pressure of any system.

e. Counter Balance Valve:

These are used to develop pressure in the reverse direction at the actuator's return line in order to keep the load under control.

f. Sequence Valve:

These are used to maintain sequence or order in the operations of two parts or branches.

A cylindrical bar of steel 10.1 mm (0.3976 in.) in diameter is to be deformed elastically by application of a force along the ba
Nina [5.8K]

Answer:

given d= 10.2x10-3m

change in diameter d' =3.4x10-6 m

elastic modulus=207x109pa

1/m=0.30

we know that stress/strain=E

but poissons ratio 1/m = lateral starin/longitudinal starin

0.3= (d'/d)/(L'/L)

L'/L = 3.4x10-6/(0.3x10.2x10-3)

= 1.11*10-3

E= (f/A)/(L'/L)

force f= E*A*(L'/L)

f =(1.11*10-3)*207*109*(3.1415*(10.2*10-3)2)/4

= 18775.2N =18.775KN

Explanation:

The force that produce an elastic reduction is 18.775KN

Tiny hydrogen bubbles are being used as tracers to visualize a flow. All the bubbles are generated at the origin (x = 0, y = 0).
notka56 [123]

Answer:

for t = 1 : ( x1 , y1 ) = (1,2)

for t = 2 : ( x2, y2 ) = (2,4)

for t = 3 : ( x3, y3 ) = ( 0,-3)

for t = 4 : ( x4, y4 ) = ( 0,-4)

Explanation:

Attached below is the detailed solution and the sketch

we have to make assumptions for the various values of t and integrate accordingly

for t = 1 : ( x1 , y1 ) = (1,2)

for t = 2 : ( x2, y2 ) = (2,4)

for t = 3 : ( x3, y3 ) = ( 0,-3)

for t = 4 : ( x4, y4 ) = ( 0,-4)

Given data :

origin ( x = 0, y = 0 )

u = 1 m/s,  v = 2 m/s,

0 \leq t < 2s  where u = 0 m/s   v = -1 m/s

Gold forms a substitutional solid solution with silver. Compute the number of gold atoms per cubic centimeter for a silver-gold
evablogger [386]

Answer:

Compute the number of gold atoms per cubic centimeter = 9.052 x 10^21 atoms/cm3

Explanation:

The step by step and appropriate substitution is as shown in the attachment.

From number of moles = Concentration x volume

number of moles = number of particles/ Avogadro's number

Volume = mass/density, the appropriate derivation to get the number of moles of atoms

I need answers for both questions. thank u if u help.
My name is Ann [436]

Answer:

a. Greater the mass, larger the crater

b. Greater the speed, larger the crater

Explanation:

a. They key to answering both questions is understanding that the crater produced by an object is as a result of the force that the object applies when it hits the ground. If it applies a lot of force, a larger crater is produced.

Force is calculated by multiplying mass and acceleration. This means that if either of these is high, the force will be grater and the crater will therefore be larger as well.

Explicitly said, the greater the mass of an object, the larger the size of the crater that it will create.

b. The greater the speed of an object, the larger the size of the crater that it will create as well.
