Unit 1
Force=?
MassxAcceleration
The examination of models, systems, processes, and elements of nature to design solutions to human problems.
Biomimicry
Fluid power system (Name both)
Hydraulics system and Pneumatics system
Formula for σ(stress)
Force/Area or E·ε
What are the simple machines? (Name all six)
Inclined plane, wedge, screw, lever, pulley and wheel-and-axle.
What is a closed loop system?
A system where a portion of the output is fed back to the input to influence the system's operation.
What is a multimeter?
Measures voltage, current, and resistence.
What is a force vector?
Vector quantities, such as weight, acceleration, velocity, and force are fully described when both magnitude and direction are considered.
A repeated, curved, back and forth movement that pivots about an axis.
Oscillating motion.
The involvement of the public in scientific research.
Citizen science.
What is a series circuit?
All the loads are on the same wire. Same Path.
For every action force, there is an equal and opposite reaction force. This law describes action-reaction pairs. Force pairs act in opposite directions and have the same magnitude.
Newtons Third Law of Motion
What is Machinal Advantage?
The measure of how much easier a machine makes a job.
What is a potentiometer?
To adjust resistance in a circuit, essentially acting as a variable resistor.
Req = R1 + R2 + ... + Rn
Equivalent resistance
What is Beam Deflection?
The bending or displacement of a beam when subjected to external forces or loads.
Ideal mechinal advantage equation?
Effort distance(in)/Resistance distance(out)
What is the KNN?
K-nearest-neighbor is a data classification algorithm.
(Used to teach robots.)
In a series there is a 50V battery and 3 resistors, resistor one is 25V, two is 13V, and three is 7V. What are the color bands of resistor two?
Brown, orange, black.
Qavg=∑Qi/n
Average flow rate.
