QUESTIONS TO ADDRESS: What was presented in the LO 3 was only our best guess as to what was used at the CCF. Investigate the various ways horses could be harnessed to produce power
...to what kind of uses was horse power used?

INTERVIEW the oldest folks you can whether they remember horse power being used? ...how and for what purpose was it used? …was it transportable or built-in to a building?

QUESTIONS TO ADDRESS: Investigate when belt & pulley systems first came to be used.
...what purpose were they intended to serve?
...what advantages/disadvantages did they have over alternatives?

Clutches were always needed in such a system... why?

INVESTIGATE a modern example from a car, mower, ATV, whatever ...and compare the clutch as used in the CCF with clutches as still used, today.

QUESTIONS TO ADDRESS: How is power calculated?... what two factors must be included?
[what weight...can be moved what distance...]

CALCULATE: how does that work out in the CCF powertrain?
[whatever 2 horses can pull, around an 8'circle in a minute]
If the speed and force which are transmitted from wheel to wheel by belts, is directly proportional to the relative size of the two wheels...calculate how the speed of these plodding horses increases, at each step through the power system, and how much force is lost to gain this speed.

TRY to calculate the speed of the wood piece being turned in the lathe?...in rpm [revolutions per minute]

Learning Objectives

The “Two Horse Power” Learning Object is designed for students and educators to meet the following objectives:

• Learn about early sources of power;

• Explore the period of Canadian history when the increasing reliance upon power changed our culture and explore what impact that might have had on the human workforce;

• Identify, research and describe the possible uses and arrangements for horse power;

• Learn about the differences and similarities between systems of gears and systems of belts & pulleys for the transmission and distribution of power;

• Establish links between the function of a “clutch” in traditional belt & pulley system and the use we make of them today in mowers, snowmobiles and ATVs;

• Identify, research, and practice using the equations which enable us to calculate the mechanical advantages to be gained in the transmission of power;

• Demonstrate an understanding of how systems of gears and belts & pulleys rely upon the principles already evident in the simplest machines.
