Answer:

A. engineering design process

Explanation:

We are told that John is trying to develop a handheld camera. And that it is unlike any other one that has been developed before.

Now, though he understands what the final product will look like, the camera still required further development and modification. This is simply an engineering design process because it involves finding a need and trying to solve it since he already understands what the final product will be.

Hope this helps you and others

30,000 parts

A single car has about 30,000 parts, counting every part down to the smallest screws.

The total number of parts (screws and bolts included) of the average car is around 30,000.

The radiator can be described as a heat exchanger used to eliminate heat from the coolant in the cooling system to prevent the vehicle’s engine from overheating. The hot coolant is routed via the radiator, where the coolant exchange heat with the passing air.

The AC Compressor pumps coolant throughout the system and starts the process of the cooling car. The battery saves energy in chemical form so it is released as electricity to run the vehicle’s electrical components.

The front and rear axles are supporting a vehicle where the wheel hubs are attached. Axles are part of the suspension system and are responsible for delivering power to the wheels from the engine via the transmission and differential.

A car’s brakes can be used to stop or slow a vehicle or prevent it from moving when parked or stopped.

Answer:

The main cables of the Golden Gate Bridge are made of numerous smaller cables because by combining several thousand in number of smaller cables, each having a diameter which is approximately the diameter of a pencil, into the required cable diameter dimensions, the flexibility, strength, resistance to cracking, rotation resistance, crushing resistance and fatigue resistance of the main cables are increased, and failure of a few strands in a multi-stranded cable is more likely to be detected before catastrophic failure takes place than in a single cable

The properties of strength and flexibility that the cable provides are required so that the bridge can better cushion the seismic turbulence of the water and strong wind energy at the bay of San Francisco, the location of the bridge

Answer:

I think its aircraft carrier

Explanation:

In the early 1900s, aircraft carrier was developed and used that opened the door for naval use of aircraft.

A vessel that acts as a seagoing airbase and has a full-length flight deck as well as spaces for storing, preparing for deployment, and bringing back aircraft is known as an aircraft carrier.

Since then, the number of routes has continuously decreased. Throughout the 1990s, it remained at 12 carriers, and after 9/11, it dropped to 11 in 2007.

Congress authorised a minimum force of 11 carriers in 2011 because of concern that the number of aircraft will decline much further. Ten aircraft carriers from the Nimitz class are active in the US Navy.

A battleship that only serves as a seagoing airbase, equipped with a full-length flight deck with areas for deploying and retrieving aircraft, is called an aircraft carrier.

Thus, the answer is aircraft carrier.

Answer:

The car's position at 3.0 seconds is 17.5 meters. The car will reach 0.0 meters at 10 seconds.

Explanation:

You can rewrite the equation as P= -2.5t+25. t=time and P is equal to position; so you will plug in 3.0 seconds into t. The equation will now look like: P = -2.5(3.0)+25

P = -2.5(3.0) + 25

P = -7.5 + 25

P = 17.5 meters

Now, to find when the car reaches 0.0 meters, we will plug that into P since P = position and will solve for t.

P = -2.5t + 25

0.0 = -2.5t + 25

-25                 -25

-25 = -2.5t

-25/-2.5 = -2.5t/-2.5

10 = t

So the car will reach 0.0 meters at 10 seconds.

In other words, an object possesses mechanical energy when it has the ability to do work due to its position or motion. Mechanical energy can take the form of either kinetic energy, which is energy due to an object's motion, or potential energy, which is stored energy due to an object's position.

Some examples of mechanical energy are:

This refers to the type of energy that an object or mass possesses based on its motion and can either be potential or kinetic energy.

Therefore, mechanical energy can be represented mathematically as: [tex]E_{mechanical}[/tex] = U + K

Where U= potential energy

K= kinetic energy

Answer:

1) The speed of the roller coaster at the bottom is approximately 15.65 m/s

2) The acceleration of the roller coaster at the bottom is 6·g's

3) The high acceleration is 6 times the force of the weight of the  passengers

The high acceleration can cause gravity induced loss of consciousness

4) Please find attached a force diagram of the forces at the bottom of the roller coaster created with Microsoft Visio

5) For the acceleration at the bottom to be 2·g's the radius of the rollercoaster at the bottom should be 25 meters

5) The radius at the bottom of roller coasters are increased to reduce the normal force felt by the passengers as they pass the bottom of a circular roller coaster

Explanation:

1) The given parameters are;

The radius of the roller coaster, r = 5.0 m

The speed of the roller coaster = Minimum = 0 m/s

The shape of the roller coaster's path = Circular loop

Therefore, the maximum height of the roller coaster, h = The diameter of the of a circular path of the roller coaster, d = 2 × r = 2 × 5.0 m = 10.0 m

∴ h = 10.0 m

The minimum speed is f=given by the following equation;

[tex]F_N = \dfrac{m \cdot v^2}{R} - m \cdot g = 0 \ (At \ the \ top \ of \ the \ roller \ coaster's \ path)[/tex]

Therefore, we have;

[tex]\dfrac{m \cdot v^2}{R} = m \cdot g[/tex]

From which we have;

v = √(R × g)

Where;

R = The radius of the path of the roller coaster = 5.0 m

g = The acceleration due to gravity = 9.8 m/s² = constant

By plugging in the values of the variable, 'R', and the constant, 'g', we get;

v = √(5.0 m × 9.8 m/s²) = 7 m/s

The minimum speed of the roller coaster, v = 7 m/s

The speed of the roller coaster at the bottom is given by the conservation of energy formula as follows;

The energy at the top of the roller coaster = The energy at the bottom of the roller coaster

∴ The total mechanical energy of the roller coaster, M.E., is constant and at the top, [tex]M.E._{top}[/tex], is given as follows;

[tex]M.E._{top}[/tex] = 1/2·m·v₁² + m·g·h₁

At the bottom, the total mechanical energy is given as follows;

[tex]M.E._{bottom}[/tex] = 1/2·m·v₂² + m·g·h₂

Where;

v₁ = The velocity of the roller coaster at the top = 7 m/s

h₁ = The height of the roller coaster at the top = 10 m

v₂ = The speed of the roller coaster at the bottom

h₂ = The height of the roller coaster at the bottom = 0 m

g = The acceleration due to gravity = 9.8 m/s² = Constant

By plugging in the values, we get;

M.E. = [tex]M.E._{top}[/tex] = [tex]M.E._{bottom}[/tex]

∴ 1/2·m·v₁² + m·g·h₁ = 1/2·m·v₂² + m·g·h₂

1/2 × (7 m/s)² + 9.8 m/s² × 10.0 m = 1/2 × v₂² + 9.8 m/s² × 0 m

122.5 m²/s² =  1/2 × v₂²

∴ v₂² = 2 × 122.5 m²/s² = 245 m²/s²

v₂ = √(245 m²/s²) = 7·√5 m/s ≈ 15.65 m/s

The speed of the roller coaster at the bottom, v₂ ≈ 15.65 m/s

2) The normal force on the car at the bottom of the roller coaster is given as follows;

[tex]F_N = \dfrac{m \cdot v_2^2}{R} + m \cdot g = m \times \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

Force, F = Mass, m × Acceleration, a

∴ F = m×a

Therefore, the acceleration at the bottom, 'a' by comparison of the general equation for force, 'F', and the normal force, [tex]F_N[/tex], is given as follows;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

Plugging in the values for 'v₂²', 'R', ang 'g', gives;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right ) = \left(\dfrac{ 245}{5} + 9.8 \right ) = \left(49+ 9.8 \right ) = (5 + 1) \times 9.8 = 6 \times 9.8 = 6 \times g[/tex]

a = 6·g = 58.8 m/s²

3) The high acceleration will lead to a very high normal force (equal to 6 times each of their weight) experienced by the passengers with a force

The high acceleration is dangerous and can lead to gravity induced loss of consciousness since it is more than 3·g's

4) Please find attached the force diagram at the bottom of the roller coaster created with Microsoft Visio

5) For the acceleration at the bottom to be 2·g's, we have;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

At a = 2·g, we have;

[tex]2 \cdot g = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

[tex]\therefore 2 \cdot g - g = g = \dfrac{ v_2^2}{R}[/tex]

[tex]R = \dfrac{ v_2^2}{g} = \dfrac{245}{9.8} = 25[/tex]

R = 25 m

The radius at the bottom of the roller coaster should be 25 meters so that only 2·g's is felt

5) The shape of the roller coaster has an increases the radius at the bottom so as to reduce the acceleration of the car

Answer:

S2 = 60 RPM.

Explanation:

Given the following data;

Gear ratio = 40/24 (T2 = 40 and T1 = 24).

Speed of driving gear = 100 RPM

To find the speed of the driven gear;

Mathematically, gear ratio in terms of speed (RPM) is given by this formula;

[tex] S_{1} * T_{1} = S_{2} * T_{2} [/tex]

Where;

Substituting into the equation, we have;

[tex] 100 * 24 = S_{2} * 40[/tex]

[tex] 2400 = 40S_{2} [/tex]

[tex] S2 = \frac {2400}{40} [/tex]

S2 = 60 RPM.

Therefore, the speed of the driven gear is 60 revolutions per minute.
