5. Machines
Definition of Machine:
A machine is a device that uses energy to perform some activity or task.
A machine (or mechanical device) is a mechanical structure that uses power to apply forces
and control movement to perform an intended action. Machines can be driven by animals
and people, by natural forces such as wind and water, and by chemical, thermal, or electrical
power, and include a system of mechanisms that shape the actuator input to achieve a
specific application of output forces and movement. They can also include computers and
sensors that monitor performance and plan movement, often called mechanical systems.
A Machine is an artificial object that takes in inputs and produces useful outputs
A Processor is an object that takes in inputs and produces useful outputs

10. Science of Engines (Thermodynamics)
Ideal Gas Law: PV = nkT
Pressure * Volume = Number of Molecules * Constant * Temperature in Kelvin
Work = Force * Distance
Power = Work/Time
F = M *A
Force =- Mass * Acceleration
12. Calculating Engines
Charles Babbage 1871
Ada Lovelace
Programmer
Analytic Engine
Difference Engine
Was supposed to calculate values
of polynomials. Finally built in 1989
Polynomial = 2 + 3 * x + 5*x^2 ….
General Purpose Computer. Never built.

15. Electricity
Edison (DC)
Faraday
Maxwell 1855
Tesla (AC)
Ohm’s Law
V = I * R
Voltage = Current * Resistance
Ohm
Charge produces electrical field
No magnetic charge (monopole)
Changing magnetic field
produces electric field
Current + Changing electrical
field produces magnetic field
Lorenz Force Law
F = qE + qv × B.
Light is Electromagnetic Wave
E = Electric Force
B = Magnetic force
c = Speed of Light
Tesla
Kirchoff Laws
Sum of Currents at Nodes = 0
Sum of Voltages in Loop = 0
Watts = Voltage * Current
