Cards (25)

Light dependent resistor 
(Generally use the left one)
Resistors 
Use the box ones
Resistors control the current flowing
Capacitors 
Store electrical charge for short periods
Protection devices
Fuse
Cells and Batteries 
More than one cell is generally called a battery
Switches 
Open
Transformer
Step up or step down the current
LED  
Light emitting diode
Diode 
Lets the current only flow one way
Rectifiers 
Convert AC to DC, using a series of diodes
Voltage Regulators 
Zener diode - Reduces voltage, whilst getting rid of fluctuations. Also can pass current in both directions but retains constant voltage
Transistors 
Can amplify and switch current
KERS 
Kinetic Energy Recovery System, can be used on both electric and mechanical braking systems
Orders of Levers 
FLEX
First order - Fulcrum is in the middle
Second order - Load is in the middle
Third order - Effort is in the middle
Biomaterials 
creating the biomedical structures and devices to replace biological function.
Biomechanics 
applying the principles of engineering mechanics in the understanding of the function of cell and whole organ systems in healthy and diseased states
Biosignals 
developing software and technology for monitoring areas such as the brain (neuroimaging - EEG), heart (ECG) and muscle activity
Biocomputing 
using computer technology to model, investigate and provide medical solutions to biological systems
Rehabilitation engineering 
the design and development of rehabilitation devices such as walking frames and wheelchairs
Ethics and engineering
Demonstrate integrity
Practise competently
Exercise leadership
Promote sustainability
Mechanical Advantage
MA = L/E = Load/Effort
Velocity Ratio 
VR = d of effort / d of load = d in / d out
Distance that you push something vs how far it goes.
Efficiency
If 100% efficient, MA = VR
η = MA/VR * 100%
Nut and etc dimensions
