The OBLIQUE different objects below are the1, 3, and 6 in the picture given below.

<h3>What is an OBLIQUE object ?</h3>

A projective drawing of which the frontal strains are given in proper proportions and members of the family and all others at appropriate angles aside from ninety levels without regard to the guidelines of linear perspective.

Oblique drawings are drawn with one plane (front) of the item parallel to the drawing surface. The aspect, or difference seen a part of the item is normally drawn at 30◦ or 45◦. Note that simplest the aspect is on an angle. In many instances, those sorts of drawings aren't interested in scale.

Rewrite the following nested if-else statement as a switch statement that accomplishes exactly the same thing. Assume that num i

seropon [69]

Answer:

Answer explained below

Explanation:

The following is the nested if-else statement:

% if-based statement

if num < -2 || num > 4

f1(num)

else

if num <=2

if num >= 0

f2(num)

else

f3(num)

end

else

f4(num)

end

<u>NOTE:</u> the num is an integer variable that has been initialized and that there are functions f1, f2, f3 and f4.

The nested if-else statement can be replaced by switch statement as shown below:

switch num

case(0, 1, 2)

f2(num)

case(-2, -1)

f3(num)

case(3, 4)

f4(num)

otherwise

f1(num)

In this case, the switch based code is easier to write and understand because the cases are single valued or a few discrete values (not ranges of values)

For a metal that has a yield strength of 690 MPa and a plane strain fracture toughness (KIc) of 32 MPa-m1/2, compute the minimum

Digiron [165]

Answer:

the minimum component thickness for which the condition of plane strain is valid is 0.005377 m or 5.38 mm

Explanation:

Given the data in the question;

yield strength σ $_y$ = 690 Mpa

plane strain fracture toughness K $_{Ic$ = 32 MPa- $m^{1/2$

minimum component thickness for which the condition of plane strain is valid = ?

Now, for plane strain conditions, the minimum thickness required is expressed as;

t ≥ 2.5( K $_{Ic$ / σ $_y$ )²

so we substitute our values into the formula

t ≥ 2.5( 32 / 690 )²

t ≥ 2.5( 0.0463768 )²

t ≥ 2.5 × 0.0021508

t ≥ 0.005377 m or 5.38 mm

Therefore, the minimum component thickness for which the condition of plane strain is valid is 0.005377 m or 5.38 mm

A gas cylinder is connected to a manometer that contains water. The other end of the manometer is open to the atmosphere, which

horrorfan [7]

Answer: the absolute static pressure in the gas cylinder is 82.23596 kPa

Explanation:

Given that;

patm = 79 kPa, h = 13 in of H₂O,

A sketch of the problem is uploaded along this answer.

Now

pA = patm + 13 in of H₂O ( h × density × g )

pA= 79 + (13 × 0.0254 × 9.8 × 1000/1000)

pA = 82.23596 kPa

the absolute static pressure in the gas cylinder is 82.23596 kPa

Calculate the volume of a hydraulic accumulator capable of delivering 5 liters of oil between 180 and 80 bar, using as a preload

Vinil7 [7]

Answer:

1) $V_o = 10 liters$

2) $V_o = 12.26 liters$

Explanation:

For isothermal process n =1

$V_o =\frac{\Delta V}{(\frac{p_o}{p_1})^{1/n} -(\frac{p_o}{p_2})^{1/n}}$

$V_o = \frac{5}{[\frac{72}{80}]^{1/1} -[\frac{72}{180}]^{1/1}}$

$V_o = 10 liters$

calculate pressure ratio to determine correction factor

$\frac{p_2}{p_1} =\frac{180}{80} = 2.25$

correction factor for calculate dpressure ration for isothermal process is

c1 = 1.03

$actual \ volume = c1\times 10 = 10.3 liters$

b) for adiabatic process

n =1.4

volume of hydraulic accumulator is given as

$V_o =\frac{\Delta V}{[\frac{p_o}{p_1}]^{1/n} -[\frac{p_o}{p_2}]^{1/n}}$

$V_o = \frac{5}{[\frac{72}{80}]^{1/1.4} -[\frac{72}{180}]^{1/1.4}}$

$V_o = 12.26 liters$

calculate pressure ratio to determine correction factor

$\frac{p_2}{p_1} =\frac{180}{80} = 2.25$

correction factor for calculate dpressure ration for isothermal process is

c1 = 1.15

$actual \volume = c1\times 10 = 11.5 liters$
