To achieve maximum output, the four strain gauges should be arranged in a full-bridge configuration on the cantilever beam.

To maximize the output of the Wheatstone bridge with four strain gauges attached to a cantilever beam for measuring load 'f', the strain gauges should be arranged in a specific configuration called a full-bridge configuration.

In a full-bridge configuration, two strain gauges are placed on the top surface of the cantilever beam, while the other two strain gauges are placed on the bottom surface.

The strain gauges on the top surface are arranged parallel to each other, and the strain gauges on the bottom surface are also arranged parallel to each other.

The Wheatstone bridge consists of four resistive elements, where each strain gauge represents one element.

The strain gauges are connected to form a closed loop with a power supply and an output measurement point.

The bridge is typically powered by a constant current source.

By arranging the four strain gauges in this manner, any changes in the resistance of the strain gauges due to the applied load will result in a change in the bridge output voltage.

The full-bridge configuration provides the maximum sensitivity and output signal for accurate load measurements.

When the load 'f' is applied to the cantilever beam, it causes the strain gauges to experience a change in resistance.

This change in resistance creates an imbalance in the Wheatstone bridge, resulting in a non-zero output voltage.

By measuring this output voltage, the applied load 'f' can be determined accurately.

It is important to note that the specific positioning and orientation of the strain gauges may vary depending on the design and requirements of the cantilever beam and the desired load measurement accuracy.

Consulting the manufacturer's guidelines or specific engineering standards is recommended for precise placement of the strain gauges to achieve maximum output in a given application.

Answer:

No, the velocity profile does not change in the flow direction.

Explanation:

In a fluid flow in a circular pipe, the boundary layer thickness increases in the direction of flow, until it reaches the center of the pipe, and fill the whole pipe. If the density, and other properties of the fluid does not change either by heating or cooling of the pipe, then the velocity profile downstream becomes fully developed, and constant, and does not change in the direction of flow.

Answer:

1279

Explanation:

We have the mean u = 1497

Standard deviation sd = 322

We find the x distribution using 25%

P(Z<z) = 0.25

Z = -0.675

From here we use the formula for z score

X = z(sd) + u

X = -0.675*322 + 1497

X = -217.35 + 1497

X = 1279.6

Which is approximately 1279

So we conclude that the maximum sat scores in year 2014that meets with the requirements of this course is 1279

The answer is "+9.05 kw"

Explanation:

In the given question some information is missing which can be given in the following attachment.

The solution to this question can be defined as follows:

let assume that flow is from 1 to 2 then

Q= 1kw

m=0.1 kg/s

From the steady flow energy equation is:

\(m\{n_1+ \frac{v^2_1}{z}+ gz_1 \}+Q= m \{h_2+ \frac{v^2_2}{2}+ gz_2\}+w\\\\\ change \ energy\\\\0.1[1.005 \times 800]-1= 0.01[1.005\times 700]+w\\\\w= +9.05 \ kw\\\\\)

If the sign of the work performed is positive, it means the work is done on the surrounding so, that the expected direction of the flow is right.

The deceleration required to comply with the speed limit before being caught by the camera is 6.094 meters per square second.

Let assume that the motor car decelerates at constant rate. Given the initial and final speeds (\(v_{o}\), \(v\)), in meters per second, and travelled distance (\(s\)), in meters, the deceleration (\(a\)), in meters per square second, is determined by this formula:

\(a = \frac{v^{2}-v_{o}^{2}}{2\cdot s}\)

If we know that \(v_{o} = 25\,\frac{m}{s}\), \(v = 40\,\frac{m}{s}\) and \(s = 80\,m\), then the deceleration required to comply with the speed limit is:

\(a = \frac{\left(25\,\frac{m}{s} \right)^{2}-\left(40\,\frac{m}{s} \right)^{2}}{2\cdot (80\,m)}\)

\(a = -6.094\,\frac{m}{s^{2}}\)

Gasoline is injected directly into the cylinder.

Explanation:

In a direct injection system, the air and gasoline are not pre-mixed. Rather, air comes in using the intake manifold, while the gasoline is injected directly into the cylinder.

At the rubber-nitrogen interface, the mass density is 0.1092 kg/m3.

The weight of an object—which is determined by multiplying its mass by the gravitational acceleration—determines the force of gravity acting on it, or w = mg. Given that weight is a force, the SI unit for weight is the newton. Density is equal to mass/volume.

Measures of mass (weight). The metric system of measuring employs the gram (g), kilogram (kg), and tone as its mass units (t). The mass density of a substance, material, or item is a measurement of its mass (or number of particles) in relation to the volume it occupies.

The answer for the ideal mechanical advantage and actual mechanical advantage for the different scenarios are;

A) Ideal Mechanical Advantage = 18.67

B) Actual Mechanical Advantage = 4.1067

We are given;

Input distance; The diameter of the wheel; d_w = 14 inches

Output distance; The diameter of the axle that drives the wheel; d_a = 3/4 inches

The force needed to cut a one-inch-thick softwood board; F = 1.75 pounds

The efficiency of the band saw; η = 22% = 0.22

A) Formula for Mechanical advantage is;

M.A = Force output/Force input = (Input distance)/(Output distance)

Thus;

Ideal mechanical advantage = 14/(3/4)

Ideal mechanical advantage = 18.67

B) Now, we are given that efficiency of the band saw is η = 22% = 0.22.

Thus using the mechanical advantage formula above;

Actual mechanical advantage = 0.22 × Expected output

Actual mechanical advantage = 0.22 × 18.67

Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Explanation:

Given that;

Weight of soil r = 118 lb/ft³

stress parameter C = 250 lb/ft²

φ total = 29°

depth Z = 12 ft

The shear strength on a horizontal plane at a depth of 12ft

ζ = C + δtanφ

where δ = normal stress

normal stress δ = r × z = 118 × 12 = 1416

so

ζ = C + δtanφ

ζ = 250 + 1416(tan29°)

ζ = 250 + 1416(tan29°)

ζ = 250 + 784.9016

ζ = 1034.9015 lb/ft²

Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Yes, it is possible to obtain the Laplace transform of the heat transfer equation.

The Laplace transform is an essential tool in solving differential equations because it converts differential equations into algebraic equations that can be quickly solved.The heat transfer equation is given by:Q = mc(T)/dtTaking the Laplace transform of both sides, we have:L(Q) = L(mc(T))/L(dt)Using the property of the Laplace transform, L(d/dt f(t)) = sL(f(t)) - f(0), we have:L(Q) = L(mc(T))/sThe Laplace transform of mc(T) can be evaluated as follows: L(mc(T)) = m*c* L(T)Applying the Laplace transform on both sides of the equation dT/dt = Q/mc, we have:L(dT/dt) = L(Q/mc)Using the property of the Laplace transform, L(d/dt f(t)) = sL(f(t)) - f(0), we have:sL(T) - T(0) = L(Q)/mcRearranging, we get:L(T) = (1/ms)(L(Q)/c + T(0))Thus, the Laplace transform of the heat transfer equation is:L(T) = (1/ms)(L(Q)/c + T(0))

Answer:

(i) The inductance of the inductor is = 43.43 mH (ii) the impedance of the circuit is = 16∠58.61° Ω (iii) the phase difference for current and the voltage applied is Q = 58.61°

Explanation:

Solution

Given that:

I= 5 A

V = 125V

Resistance R= Not known yet

Thus

To find the resistance we have the following formula which is shown below:

R = V/I

=125/15

R =8.333Ω

Now,

Voltage = 240

Frequency = 50Hz

Current (I) remain at = 15A

Z= not known (impedance)

so,

To find the impedance we have the formula which is shown below:

Z = V/I =240/15

Z= 16Ω⇒ Z = R + jXL

Z = 8.333 + jXL = 16

Thus

√8.333² + XL² = 16²

8.333² + XL² = 16²

XL² = 186.561

XL = 13.658Ω

Now

We find the inductance of the Inductor and the impedance of the circuit.

(i) In solving for the inductance of the inductor, a formula is applied here, which is shown below:

L =  XL/w

=13.658/ 2π * 50

=13.658/314.15 = 0.043 = 43.43 mH

Note: w= 2πf

(ii) For the impedance of the circuit we have the following:

z = 8.333 + j 13.658

z = 16∠58.61° Ω

(iii) The next step is to find the phase difference between the applied voltage and current.

Q =  this is the voltage across the inductor in a series of resonant circuit.

Q can also be called the applied voltage

Thus,

Q is described as an Impedance angle

Therefore, Q = 58.81°
