Answer:

Part 1

4 mm⁴

Part 2

32 cm³

Explanation:

Part 1

The diameter of the circular cross section, d = 3 mm

The area moment of inertia of a circle, [tex]I_C[/tex], is given as follows;

[tex]I_x = I_y = \dfrac{\pi \cdot d^4 }{64}[/tex]

Where;

d = The diameter of the circle

Therefore, the area moment of inertia of the given circular cross section, with d = 3 mm, is found as follows;

[tex]I_x = I_y = \dfrac{\pi \times (3 \, mm)^4 }{64} \approx 4 \, mm^4[/tex]

Part 2

The minimum area moment of inertia for a rectangular cross-section is given as follows;

[tex]I_x = \dfrac{1}{12} \cdot b \cdot h^3[/tex]

[tex]I_y = \dfrac{1}{12} \cdot h \cdot b^3[/tex]

The minimum moment of inertia, for the rectangular cross-section is given by placing, the height, h = The short side length and calculating for, Iₓ, and vice versa

Therefore, for the question, where, h = 4 cm, and b = 6 cm, we have;

[tex]I_x = \dfrac{1}{12} \times 6 \, cm \times (4 \, cm)^3 = 32 \, cm^4[/tex]

4.75cm * 5.22cm is 24.795cm²

but let's do this with m² instead:

0.0475m * 0.0522m = 0.0024795

now we can compare it with the 49780 much easier.

devide. that's the roughly 20,000,000fold of the plot, but it's still squared, so let's take the root

so the representative fraction is 1:4,480.

the exact value is in the screens

have a nice day:)

Esta es una lista de agencias bajo el Departamento de Defensa de los Estados Unidos (DoD) que anteriormente y poco antes se conocía como el Establecimiento Militar Nacional. Sus principales responsabilidades son controlar las Fuerzas Armadas de los Estados Unidos. El Departamento fue establecido en 1947 y actualmente se divide en tres departamentos principales:

el Departamento del Ejército, la Armada y la Fuerza Aérea, y tiene un personal militar de 1.418.542 (553.044 del Ejército de los EE. UU.; 329.304 de la Armada de los EE. UU.; 202.786 del Cuerpo de Marines de los EE. UU.; 333.408 de la Fuerza Aérea de los EE. UU.). [1] El Departamento de Defensa está encabezado por el Secretario de Defensa. Actualmente, el Departamento de Defensa está dirigido por el secretario de Defensa Lloyd Austin.

Answer:  

Airbags will deploy in almost any angle.

Explanation:

Cars have sensors around them, so when the car gets hit, the sensors detect a crash and deploy the airbags to keep you safe.

Answer to the following question is as follows;

Explanation:

The regulations change made two-stroke bikes “outmoded” in six years. Casual fans and industry experts alike generally credit the advancement of progress and the necessity to decrease emissions as the major causes that led to the extinction of two-stroke-powered dirt equipment.

In a two-stroke engines, the conclusion of the combustion cycle and the start of the compression stage happen concurrently, as do the inlet and exhaust operations.

Answer:

1028.1184 Ohms

Explanation:

Given the following data;

Assuming the temperature coefficient of resistance for carbon at 0°C is equal to 0.0006 per degree Celsius.

To find determine its new resistance, we would use the mathematical expression for linear resistivity;

[tex] R_{89} = R_{0} + R_{0}(\alpha T) [/tex]

Substituting into the equation, we have;

[tex] R_{89} = 976 + 976*(0.0006*89) [/tex]

[tex] R_{89} = 976 + 976*(0.0534) [/tex]

[tex] R_{89} = 976 + 52.1184 [/tex]

[tex] R_{89} = 1028.1184 \ Ohms [/tex]

Apply the brakes.

Keep your eyes on the road and look for a way out.

Warn other drivers by blinking and flashing your hazard lights.

Try to drive the car safely off the road.

Turn off the ignition when you no longer need to change direction.

Answer:

-3/x^2

Explanation:

Deriving is a lot like taking one away from the exponent. With that in mind, lets rewrite 3/x into 3x^-1. All we need to do is bring down the negative one then subtract one from the exponent. This gives us -3x^-2. We can convert it back to -3/x^2 .

Explanation:

Answer: 300 ft

Explanation:

This question is based on Indiana State Driving codes.

According to Indiana regulations, if you are going at a speed of 50 miles per hour or above, you should begin to indicate your desire to turn or change lanes at least 300 feet before you do.

This would give the person behind you ample time to react as they might be going at the same speed as you. The rules further state that the signal to use is that of the car but if it is damaged then hand signals would suffice.

Answer:

B. Acid rain.

C. Photochemical smog.

Explanation:

Oxides of nitrogen contribute to the formation of photochemical smog and acid rain. Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere while on the other hand, when nitrogen oxide react with the water vapor in the atmosphere forming nitric acid which falls on the earth surface with the help of precipitation.

Answer:

try using an App called Tinkercad

Answer:

1. a) True

2. a) True

3. a) Four-wheel anti-lock brakes

Explanation:

1. True

When a wheel skids, there is less traction with the road and the vehicle is out of the driver's control

Breaks that have ABS are prevented from functioning fully in a situation where the contact between the tire and the road patch is broken and the tire is able to skid. Once the tire regains and maintains proper contact with the road surface such that the skidding has ceased, the full functionality of the brakes are restored, enabling the moving vehicle to stop faster and the steering to remain operational

2. True

A vehicle that has a standard Electronic Stability Control, ESC, is less likely to rollover. According to a University of Michigan Transport Research Institute study, SUVs equipped with an ESC are 73% less likely to have fatal rollover crashes

3. a) Four-wheel anti-lock brakes

The four-wheel anti-lock *four-wheel ABS) brakes works such that each wheel has a sensor through which if is detected that the wheel is about to lock, the ABS, ESC releases the break pad on the wheel such that the wheel keeps spinning
