The partial di§erential equation for the small-amplitude vibrations of a string of length ` is given by A@2y@t2T@2y@x2 = 0 where y(x; t) is the vibration amplitude,  is the material density of the string, A is the string cross sectional area, and T is the tension force in the string. Using only the parameters given, make this equation dimensionless. Hint 1: first find a combination of ` and/or  and/or A and/or T to make x, y, and t dimensionless.(It is clear that a different combination will be needed to make t dimensionless than that for x and y.)

Suppose you're converting a bill of materials for machining feedstock from the British gravitational (U.S. system) of units to International System (SI) units.  Your goal is to have all of the material quantities in kilograms.  Your bill of materials lists values for required weights of brass rod in pounds.  To convert to these values to kilograms you first you divide by gravitational acceleration in feet per second squared to get a mass in slugs, then convert slugs to kilograms using standard conversion factors. Group of answer choices True False

The differential change in pressure p close to the surface of a static fluid is given by the following expression:dp/dy = -3Ap2,where A is a constant, with units of 1/(atm•m), and p is the pressure in atm. The pressure at the surface of the fluid is p(0) = 1 atm, and the coordinate y here is positive upwards with origin at the surface.  An absulute pressure gauge is placed at a depth 0.19m in the fluid. What would be the reading of the pressure gauge in units in atm? you can take the constant A=1(atm.m)^-1

Somewhere DEEP BELOW THE EARTH's surface, at an UNKNOWN displacement from the Earth's center, a particle of mass m is dangled from a long string, length L; the particle oscillates along a small arc according to the differential equation d^2x/dt^2=-(pi^2/36)x. Here x refers to an angular displacement measured from the vertical and t refers to time.  The particle's mass is given by m=3kg. The length of the string is given by L=5 meters. Whenever the particle arrives at a location of x=(pi/12) radians from the vertical, the particle has no instantaneous speed. On both sides of the vertical, that is, x=(pi/12) radians is repeatedly observed to be a 'turning point' for the particle's periodic motion. 1. Draw a clear FREE-BODY diagram of this particle at some arbitrary point during oscillation, making sure to label variables and constants described above. 2. Approximating to three significant digits if necessary, what is the angular frequency of this oscillator on a string? 3. Approximating…

Pierce (1948) mechanically measured the frequency (the number of wing vibrations per second) of chirps (or pulses of sound) made by a striped ground cricket, at various ground temperatures. Since crickets are ectotherms (cold-blooded), the rate of their philosophical processes and their overall metabolism are influenced by temperature. Consequently, there is a reason to believe that temperature would have a profound affect on aspects of their behavior, such as chirp frequency. In general, it was found that crickets did not sing at temperatures colder than 60°F or warmer than 100°F. In the following data let X= chirps/sec for the striped ground cricket and Y= temperature in degrees of Fahrenheit.  X   19      19.8        18.4     17.1     15.5    14.7     17.1    15.4    16.2    15   17.2    16     17     14.4 Y    71.6     93.3    84.3    80.6     75.2    69.7    82     69.4    83.3     79.6    82.6     80.6     83.5    76.3 a. use two decimal places: Y bar =? b. use two decimal…

PROPAGATION OF ERROR You are tasked to supervise the design of 0.5MW wind turbine to be constructed in a Wind Farm in Pililla, Rizal. Suppose the design criteria are as follows: The air density as surveyed after 2 year period averaged at 1.225 kg / cubic meter. The sweeping diameter of the rotor blades is 125m, and the anemometer reading in the area amounts to 4.2m/s on a 2 year period of survey. if the diameter measurement is off by 0.1m and the anemometer reading is also fluctuating by 0.05m/s. In the design specifications given, if the actual measurement of power via the substation amounts to exactly 530kW and given that the windspeed is off by 0.05m/s, what could have been the error in the measurement of diameter? Your answer must be in 3 decimal places and in correct signs and measurement.  Show complete solution in paper.

A flexible string 1.0 m long is connected to an oscillator. When the oscillator is set to vibrate the string at 100Hz, a standing wave is formed in the fundamental mode of oscillation. What is the speed of waves on the string?

Thermocouples are devices used to measure temperature of a given sample or the surroundingmedium. These devices feature a “bead”, which has a spherical shape, and produces voltage upon changein temperature. For an engineering application at a pharmaceutical company, thermocouple devices arebeing tested for their responsiveness, i.e. how fast it can detect temperature changes in the environment(surrounding air). The engineers at this company have specified design constraints for an idealthermocouple: it must detect temperature changes no later than 1.5 minute, and the reportedtemperature value must be reasonably correct: at most %3 difference between measured and actualtemperature values is allowed.Four thermocouples from different vendors are being tested. Relevant properties of these devices arelisted below: The experiment involves placing the thermocouple from air at 20 °C to air at 150 °C, and monitoring thetime it takes for the measured values to reach 150 °C, which is the…

Case 1: Material system without density and viscosity differences   Though unlikely in real life, in this case, we assume that all of the material in the homogenizer  is of the same density and viscosity. Thus, only one set of material parameters are mentioned  (density, ρ; dynamic viscosity, μ). The important parameters are listed as follows:   Target quantity : Mixing time, θ   Geometric parameters : Stirrer diameter, d  Material parameters : Density, ρ    Dynamic viscosity, μ  Process-related parameters : Stirrer speed, n     1.1) Write out the relevance list for Case 1.   1.2) Generate the pi-set for this case.   1.3) Write out the appropriate pi (π) numbers from the generated pi-set.  1.4) Identify the established dimensionless numbers from the derived pi (π) numbers.  1.5) Write the possible relationship of the dimensionless numbers for Case 1.

In the United States, electricity is sold using the SI units of kilowatt (kW) or megawatt (MW), and fuel for power generation stations is generally purchased using English units, e.g., British thermal unit (Btu), gallon (gal), and ton. An industrial power plant has an average annual load of 100 MW (electrical). If the overall thermal efficiency is 33% (based on HHV), what is the annual cost of fuel if the plant is fired with (a) natural gas, (b) No. 2 fuel oil, and (c) bituminous coal? Use the data from Tables 2.2, 2.7, and 2.13. Assume the cost of natural gas is $5/million Btu, the cost of No. 2 fuel oil is $3/gal, and the cost of bituminous coal is $60/ton (1 ton = 2000 lbm)

Refer to the Worksheet shown, set up to calculate the displacement of a spring. Hooke's law states that the force (F, in newtons) applied to a spring is equal to the stiffness of the spring (k, in newtons per meter) times the displacement {x, in meters): F= kx. ;Chapter 10, Problem 161CA, Refer to the Worksheet shown, set up to calculate the displacement of a spring. Hooke's law states Cell A3 contains a data validation list of springs. The stiffness (cell 83) and maximum displacement (cell C3) values are found using a VLOOKUP function linked to the table shown at the right side of the worksheet. These data are then used to determine the displacement of the spring at various mass values. A warning is issued if the displacement determined is greater than the maximum displacement for the spring. Use this information to determine the answers to the following questions. Write the expression, in Excel notation, that you would type into cell 86 to determine the displacement of the spring.…
