Explanation:

If the voltage is raised, the current will increase so long as the resistance of the circuit does not change.

As can be seen from the equation, less current will flow through if the resistance for a particular potential difference is increased. A variable resistor's passing current will be cut in half if the initial resistance is doubled.

The relationship between resistance, voltage, and current is outlined by Ohm's Law. This indicates that the current flowing through a circuit is inversely proportional to the circuit's resistance and directly proportional to the applied voltage as long as the temperature remains constant.

The angular velocity of the arm OA is equal to the angular velocity of the hub gear h, which is ωh = 3 rad/s.

To determine the angular velocity ωS of the spur gear S measured counterclockwise, we need to use the equation for the angular velocity ratio of gears, which states that the ratio of the angular velocities of two gears in contact is equal to the ratio of their diameters. In this case, the spur gear S is in contact with both the hub gear h and the ring gear r. Therefore, we can write:

ωh/ωS = Ds/Dh   and   ωS/ωr = Dr/Ds

where Dh and Dr are the diameters of the hub gear and the ring gear, respectively, and Ds is the diameter of the spur gear.

Solving for ωS in the second equation, we get:

ωS = ωr(Ds/Dr) = 22(Ds/Dr) rad/s

To find Ds/Dr, we need to use the fact that the number of teeth on the gears is proportional to their diameters. Let Nh, Nr, and Ns be the numbers of teeth on the hub gear, the ring gear, and the spur gear, respectively. Then:

Ds/Dh = Ns/Nh   and   Ds/Dr = Ns/Nr

Combining these equations, we get:

Ds/Dr = (Ns/Nh)/(Ns/Nr) = Nr/Nh

Therefore, we can substitute Nr/Nh for Ds/Dr in the expression for ωS:

ωS = 22(Nr/Nh) rad/s

To determine the angular velocity of the arm OA measured counterclockwise, we need to use the fact that the arm is attached to the hub gear h at point O and to the link BC at point A.

According to the kinetic-molecular theory, the temperature of a gas is a measure of the average kinetic energy of the gas molecules. The kinetic energy of a molecule is the energy it possesses due to its motion. As the temperature of a gas increases, the average kinetic energy of the molecules increases.

If the temperature of a gas is raised from 100°C to 200°C, the average kinetic energy of the molecules will double. This is because the temperature increase is a 100% increase, and the average kinetic energy of the molecules will also increase by 100%.

It is important to note that this is only true if the volume and number of molecules in the gas are held constant. If the volume or number of molecules changes, the relationship between temperature and average kinetic energy may be different.

The entropy change of the R134a during this process is 0.035 KJ

Entropy change refers to the measure of the degree of disorder or randomness in a thermodynamic system. It is a concept in thermodynamics that describes the amount of energy that is unavailable for doing work in a given process.

The entropy change of a system can be calculated by subtracting the initial entropy of the system from its final entropy.

T = PV/(mR)

T1 = 180 / 10 * 0.08314

T2 = P2V/(mR)

Now T1 = T2

such that

0.08314 ln (100kpa / 180)

= 0.035 KJ

The flow rate in an ideal fluid is directly proportional to the square of the radius. Flow rate is directly proportional to the fourth power of the radius of a viscous fluid. When blood is assumed to be a non-viscous fluid, the flow rate is determined to be decreased by 25% because the radius is decreased by 50%.

However, if the blood is considered a viscous fluid, the flow rate is reduced by 94.6%.Explanation:The rate of flow of fluid is defined as the volume of fluid flowing through a given cross-section of the tube in unit time. In a pipe, the rate of flow is inversely proportional to the length of the pipe, whereas it is directly proportional to the cross-sectional area of the pipe.The formula for flow rate in an ideal fluid is given by:Q = Av where,Q= flow rateA= cross-sectional areav= velocity of fluidThus, if the cross-sectional area of the tube is reduced, the flow rate will also decrease. However, in a viscous fluid, the formula changes, and the flow rate becomes:Q = (π r^4∆P) / (8ηl)where,Q= flow rateA= cross-sectional area∆P= pressure gradientη= viscosity of fluidl= length of the pipeWhen a tube is 50% blocked, the radius decreases to half of its initial value. Thus, the cross-sectional area decreases to one-fourth of the initial value because the cross-sectional area is inversely proportional to the square of the radius.If the blood is non-viscous, the flow rate decreases by 25% because the radius decreases by 50%, which is half the initial value.

Welding produces hazardous fumes and particulate matter, which can cause respiratory problems and long-term health issues.

The fumes generated during welding contain harmful substances like metal oxide, ozone, and nitrogen oxides. Inhaling these fumes can cause respiratory irritation, shortness of breath, and even lung cancer. Moreover, welding creates fine metal particles that can enter the lungs and cause damage. To protect against these hazards, welders should wear respiratory devices like respirators or air-purifying masks. These devices filter out harmful fumes and particulates, allowing the welder to breathe safely.
Fumes and ultraviolet (UV) radiation are some of the most dangerous aspects of welding. Exposure to welding fumes and UV radiation can cause significant health issues, such as respiratory problems and skin/eye damage. The best personal protection against these hazards is to wear a respiratory device, along with proper safety gear like welding helmets, gloves, and protective clothing.

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Answer:

Explanation:

The null hypothesis is that the mean fill volume is 16 oz, and the alternative hypothesis is that the mean fill volume is different from 16 oz. The level of significance is 5%, and the sample size is 15. The test statistic is t=0.0367t=0.0367. The p-value is 0.9738.

Since the p-value is greater than the level of significance, we fail to reject the null hypothesis. Therefore, there is not enough evidence to conclude that the mean fill volume is different from 16 oz. The engineer should not reset the machine.

```

The test statistic is calculated as follows:

t = (x - μ) / s / sqrt(n)

= (16.0367 - 16) / 0.0551 / sqrt(15)

= 0.0367

The p-value is calculated using the t-distribution with 14 degrees of freedom.

p-value = 2 * t.cdf(-0.0367, 14)

Centrifugal force is the force exerted on an object moving in a circular path and directed outward from the center. In order to determine the centrifugal force in pound-force of a centrifuge carrying 50mL of blood, we will need to use the formula for centripetal force:

Centrifugal force = (mass x acceleration)/radius

Here's how to solve the problem:

First, we need to determine the mass of the blood being carried by the centrifuge. We know the volume of blood (50 mL) and the density of blood (0.994 g/mL), so we can use the formula:

mass = volume x density

mass = 50 mL x 0.994 g/mL

mass = 49.7 g

Next, we need to convert the given units to SI units (meters and seconds):

Centripetal acceleration = 64 ft/s^2
1 ft = 0.3048 m
Centripetal acceleration = 64 ft/s^2 x 0.3048 m/ft = 19.5072 m/s^2

Rotational speed = 345 rpm
1 rpm = 1/60 s
Rotational speed = 345 rpm x 1/60 s = 5.75 s^-1

Now we can use the formula to calculate centrifugal force:

Centrifugal force = (mass x acceleration)/radius

The radius of the centrifuge is half the diameter (3.5 inches or 0.0889 meters):

Centrifugal force = (49.7 g x 19.5072 m/s^2)/0.0889 m

Centrifugal force = 10,879.52 N

Finally, we need to convert Newtons to pound-force:

1 N = 0.22481 lb-f
Centrifugal force = 10,879.52 N x 0.22481 lb-f/N

Centrifugal force = 2,442.69 lb-f

Therefore, the centrifugal force in pound-force is 2,442.69 lb-f.
