What is the definition of the First Law of Thermodynamics?
Energy can never be created or destroyed, it only changes form.
The slope of a stress-strain diagram in the elastic region is known as
Young's Modulus
The method to solve circuits using mesh loops
KCL
What are the three C's?
Curiosity, Connections, Create Value
The rate of heat transfer from surface contact and a temperature difference
Conduction Heat Transfer
Cycle analysis is finding the ________ of a cycle.
Efficiency
The stress acting perpendicular to the neutral axis of a beam that cause the beam to bend and fatigue
Bending Stress
A circuit component that amplifies a signal that could include voltage, current, or power into a much larger signal
Op Amp
If the P is low, the HO (original hypothesis)
has to go!
What type of heat transfer is involved with boiling water in a pot?
Convection Heat Transfer
Enthalpy is the convenient grouping of
internal energy and flow work
What is torsional stress and the equation?
Stress produced when a twisting moment is applied to an object about its axis. t=Tr/J
(T=torque, r=radius, J=polar moment of area)
The event that occurs when a conductor is placed in a changing magnetic field or a conductor moving through a fixed magnetic field produces a voltage in the conductor
electromagnetic Induction

How many full atoms does a face centered cubic have?
4 atoms
The degree of disorder or randomness in a system
Or
A quantity representing the unavailability of a system’s thermal energy for conversion into mechanical work
Entropy

live, dead, snow, rain, wind, earthquake
What are the three kinds of AC Power in the AC Power triangle?
apparent power, reactive power, and real power
What are the 5 steps to the 5S safety method?
Sort, Set in Order, Shine, Standardize, Sustain
To increase the surface area of an object and heat transfer you can add
Pressure drop due to increase in fluid friction
headloss
Forces tending to cause deformation of a material by slippage along a plane parallel to the imposed stress
Shear stress
The law that states that an induced magnetic field is opposed to the field that produces it
Lenz’ law
The ability of an engineer within an organization to be independently creative at problem solving and creating value while operating within the constraints of a larger system
Intrepreneurialism
The transfer of thermal energy by the conversion of thermal energy into electromagnetic waves at the source and the reconversion back to thermal energy at the receiver.
Radiation
