1.3 Describe how the U.S. Bureau of Labor Statistics defines an engineer and an engineering
technician (or engineering technologies) by reviewing the “field of degree” highlights for
students and job seekers in the Occupational Outlook Handbook. Describe the difference
between an engineer and a technician and provide a salary range for each
(www.bls.gov/ooh/field-of-degree).
Solution
This answer should include the salaries for an engineer (~$95,000 USD-2022) and a
technician (~$78,000 USD-2022). This may differ based on which type of engineer is chosen
from the Occupational Outlook Handbook. Answers should include the job descriptions of
each job and any notable differences. These differences may include the following: job
clearance levels, pay scale differences, educational differences, etc.
1.4 The National Society of Professional Engineers (NSPE) has established a Code of Ethics for
engineers. Look up and write down the six fundamental canons of the NSPE Code of Ethics.
Solution
1) Hold paramount safety, health, and welfare of the public
2) Perform services only in areas of their competence
3) Issue public statements only in an objective and truthful manner
4) Act for each employer or clients as faithful agents or trustees
5) Avoid deceptive acts
6) Conduct themselves honorably, responsibly, ethically, and lawfully so as to enhance the
honor, representation, and usefulness of the profession
1.5 Describe the problems with using an ancient human proportion–based measurement
system if you were to build a horse-drawn carriage and you were to purchase parts for the
carriage and horses from 12 different suppliers. You are also concerned about navigating
under a bridge that is one fathom high that you must pass under to get between your work
and your home.
Solution
Responses may include the following: The ancient method is outdated due to the form of
measurement used. Measurements were based on human portions which can vary from
person to person, leading to inconsistent measurements. A horse drawn carriage consists of
moving parts that must all simultaneously move together; if each supplier sells parts
measured to their own proportions, there could be sizing issues that do not allow the
carriage to properly function. If the underpass is sized using unique measurements, it would
offer another challenge. In short, if everything is uniquely sized with the proportions of the
manufacturers, then there are no uniform universal measurements, making it difficult to
produce anything.

1.6 Force is a derived quantity determined from the acceleration of an object multiplied by the
mass of an object. Derive the dimensions used to create units for a force acting on an object
from the fundamental quantities of length, mass, and time. Also, show the SI units of force in
your derivation.
Solution
Force = mass x acceleration (F = ma) by Newton’s Second Law
Acceleration = change in velocity over time
A = velocity/time = displacement/(time x time) = L/T x T = L/T2
F = M x L/T2
1.7 The highest mountain in the world is Mount Everest in Nepal. The peak of Mount Everest is
29,029 feet above sea level. How many miles high is this? What is the elevation in meters?
Solution
To convert from the height in feet to miles:
1 mile
29,029 ft × = 5.4979 miles
5,280 ft
To convert from the height in feet to meters:
1m
29,029 ft × = 8,848.1 m
3.2808 ft
1.8 How many bees would it take to lift the GoPro for a BeeDrone Cam?
Solution
To determine the number of bees needed:
1 bead 1 bee
159 g × × = 1,646 bees are needed to lift the GoPro
0.012 g 8 beads
1.9 How many bees can fit on top of the GoPro to carry it?
Solution
Dimensions of GoPro = 71.8 (L) x 50.8 (W) x 33.6 (H) mm
To find out the area of each side it may be useful to draw a picture. Note that the question is
how many bees can fit on top.
The top area of the GoPro is:
Area (mm2 ) = L × W = 71.8 mm × 50.8 mm = 3,647 mm2
The number of bees that fit on the top is:
1 in2 10 bees
3,647 mm2 × × = 56.53 = 56 bees can fit on the top of the GoPro
645.2 mm2 in2

1.10 How does the number of bees required compare to the number of bees that would fit on
the top of a GoPro? Does your friend’s idea have wings; that is, is the BeeDrone a good idea
or not?
Solution
There are far more bees needed to lift the GoPro (approximately 1,646 bees) compared to
how many can fit on the top of the GoPro.
The bee drone is not a good idea because a much larger number of bees are needed to lift
the mass of the GoPro than could possibly be attached to the camera.
1.11 Determine the bug weight in kilograms and enter the data from Table 1.4 into a
spreadsheet program like Excel or Google Sheets.
Solution
The bug weight in kilograms is calculated by dividing by 1000:
1 kg
0.1 g × = 0.0001 g
1,000 g

1.15 Determine the force from the impact of a bug in units of newtons for a motorcycle
traveling at 40 m/s and a 60-g bug using the previous data to interpolate the required values.
Write the relevant equations. Label your variables. Show your algebraic work and any unit
conversations required. Calculate the force associated with each different velocity and
complete Table 1.5 using a spreadsheet.
Solution
F=mxa
F = Force [N]
m = mass [kg]
a = acceleration [m/s2]
F[N] = m[kg] × a �m�s 2 � = 0.06[kg] × −7,500 �m�s 2 � = −450 [N]
Notice that the force is negative, which means the force acts opposite the direction that the
motorcycle is traveling.

1.17 Estimate the force imparted when a 60-g bug impacts an object if the speed differential
between the bug and the object is 45 m/s. Use the acceleration by interpolation or from
the graphical data. Show your calculations.
Solution
F=mxa
The trendline shows the acceleration (y) vs velocity (x) relationship. Substituting the equation
from the graph yields:
F = m × (37,922 {ln(v)} − 160,816)
F = 0.06 × (37,922 {ln(45)} − 160,816) = −9650 N
1.18 Determine the equation that relates the force imparted to a motorcycle driver at
various velocities from a curve fit of the graphical data. Use this relationship to
determine the speed that a motorcycle would have to be traveling in order to impart a
lethal force (338 N) to a motorcyclist from a 10-g cicada.

Note that 170 m/s (380 mph) is just about the land-speed record for the fastest motorcycle,
at the time of publication. The record was set by the Ack Attack motorcycle, a specially
constructed land-speed record streamliner motorcycle which set the two-way average speed
record of 605.697 km/h (376.363 mph) on September 25, 2010 in the Cook Motorsports Top
Speed Shootout at Bonneville Speedway, Utah.

from the graph yields:
F = m × (37,922 {ln(v)} − 160,816) = 338
0.010 × (37,922 {ln(v)} − 160,816) = 338
338
37,922 {ln(v)} = + 160,816 = 194,616
0.010
194,616
{ln(v)} = = 5.13
37,922
v = e5.13 = 170 m/s
Note that 170 m/s (380 mph) is just about the land-speed record for the fastest motorcycle,
at the time of publication. The record was set by the Ack Attack motorcycle, a specially
constructed land-speed record streamliner motorcycle which set the two-way average speed
record of 605.697 km/h (376.363 mph) on September 25, 2010 in the Cook Motorsports Top
Speed Shootout at Bonneville Speedway, Utah.
