3. Escapement

Clockmakers like David Rittenhouse (1732-96) and Edward Duffield (1720-1801) garnered respect comparable to the likes of political leaders Benjamin Franklin (1706-90) and Thomas Jefferson (1743-1826).

Own this I think Balance Spring oscillates. Anchor and escape wheel control the power release according to the "divided time."

1 period = the yellow dot goes from left to right and back to left.
Frequency = 1 / Time for one period
3600 per hour

Clock Escapement

Balance Wheel Frequency

For the clock in lesson 3
Tp(escape wheel) 6
Ta(escape wheel) 6
Tp(4th) 60
Ta(4th) 6
Tp(3rd) 36
Ta(3rd) 7
Tp(2nd) 70
Ta(2nd) 10

Frequency = ( 70 x 36 x 60 x 6 x 2 ) /
( 7 x 6 x 6 ) = 3600

Displacement of 70 for each each minute rotation? What is the gear train ratio(inverse)?
7/70 * 6/36 = 1/60 of 70 = 42/36 =1.16666
Displacement of 36 for each tooth of 15?


What is the frequency?
(70*36*60*15*2)/(7*6*8) = 13500/3600 = 3.75 rotation per sec
What minute is at at the 20th Displacement?
(20/70)*60=17.14
PlanetaryGearTrain
Adding 2 additional teeth to the sec gear?
Will result in 62 seconds per minute.
F = x^2 1st second has 1 tick, 2nd sec 2 so on. How many seconds have passed after 10 ticks?
