FALL2021. ME 455. Mechanical Engineering Measurements and Experiments
Experiment #1. Basic Instrumentation Name: Brandan Herrera
Lab Section: Wednesday 10:00-11:50 Group Members: Hal Vieyra, Seth Harper
Section 1. Experiment summary (15 Points)
(~250 words)
Using the different measuring devices (Oscilloscope, Function Generator, Digital Multi Meter, DC Voltage Power Supply) know how to produce different and read results. Using the function generator, generate different signals and change parameters of the signal. Using the oscilloscope, know how to read a signal by adjusting the vertical, horizontal and trigger to adjust the bounds of the wave. Using the digital
multi meter, know how to read and select the appropriate results. With the DC voltage power supply, know how to supply and measure the voltage being produced. Using resistors, be able to decipher the amount of resistance they offer through the color of the stripes on the resistor. As well as be able to combine all these different machines to be able to read multiple outputs by a single input.

Section 4. Questions (30 Points)
Question 1
: Check your RMS and Frequency measurements using OS and DMM in Table 1. Are they always very close in value? Explain your result. Answer 1:
They are pretty close in value because there is not a resistor in a DMM which would throw the values off
due to KVL. The only ones that differ are the ones where the Hz was in the mega or 10^6 Hz because the largest value that the DMM could read was in the kHz. The OS was a lot more accurate because it could withstand the voltages and Hz the function generator was throwing at it in comparison to the DMM.
Question 2
: Set OS input terminal to DC coupling, what happens to the signal shown on OS when the DC OFFSET button on FG is pressed in and adjusted off-center?
Answer 2: The DC coupling does not have any visual effects on the OS because DC coupling still has both AC and DC components. In other words, DC coupling does nothing because nothing is being added or removed from the trigger circuit. Question 3
: Set OS input terminal to AC coupling, what happens to the same signal shown on OS when the DC OFFSET button on FG is pressed in and adjusted off-center??
Answer 3:
AC coupling changed by “blocking” certain or slow varying voltages that travel through the OS after it passes through the trigger circuit. In other words, it would remove the DC components while keeping the AC coupled outputs.
Question 4: What happens to the square, triangle, and sine waves when the DUTY CYCLE is rotated clockwise and
counterclockwise? (Hint: make a chart that describes changes, if any, in the frequency, RMS voltage, rise time, fall time and overall appearance for the signals.)

QUESTION 2
Thermocouples are devices used to measure temperature of a given sample or the surrounding
medium. These devices feature a "bead", which has a spherical shape, and produces voltage upon change
in temperature. For an engineering application at a pharmaceutical company, thermocouple devices are
being 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 ideal
thermocouple: it must detect temperature changes no later than 1.5 minute, and the reported
temperature value must be reasonably correct: at most %3 difference between measured and actual
temperature values is allowed.
Four thermocouples from different vendors are being tested. Relevant properties of these devices are
listed below:
Thermal conductivity Density

A. A customer asked you to explain your choice of a temperature sensor that you used for his PCB.
Initially, there were two sensor options. To compare between them, you decided to test their accuracy
and precision. Accuracy of a sensor is a measure of how near its reading is to the real value, the nearer
the measured value to the real value the better. While precision is a measure of how widely spread the
readings of a sensor are [relative to each other] when measuring the same variable, the narrower the
spread the better. So, you tested the two sensors by measuring the same temperature, which was 100
C of boiling water, and you recorder the following 10 measurements of each sensor. Which Sensor has
higher accuracy, and which one has higher precision.

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the Ti-6Al-4V…
