מה מציינות יחידות המידה ps ?
HP בגרמנית, אם אני לא טועה. בכל מקרה זה סוג של כוח סוס, בהתאם להבדלים הקטנים שיש בין HP לBHP.
PS = Pferde Staerken (literally "horse-strength)
DIN = Deutsche Industrie Normen (German Industry Standards)
ISO = International Standards Organisation
ולהסבר די ממצה:
One SAE/British Horsepower is 746 watts/0.746 kilowatts.
One DIN/JIS HP/PS is 735.5 watts.
SAE = Society of Automotive Engineers.
DIN = International Standards Organisation.
PS = Abbreviation for German term for horsepower.
JIS = Japanese Standards Institute.
1 DIN/JIS hp = 0.986 SAE/British hp
"One horsepower provides the ability to do 550 ft-lbs of work every
second. 550 ft-lbs of work is any product of force (in pounds) and
distance (in feet) equaling that number.
Applying 55 lbs of force through a distance of 10 feet, for example,
represents the same amount of work as 11 lbs. of force applied
through 50 feet. The force can be used to lift objects against the
pull of gravity, drag them along the ground against frictional
forces, accelerate objects, etc.
A 100 HP motor would let you do 550 X 100 or 55,000 ft-lbs. of work
each second. It could, for example, lift 550 lbs. 100 feet in one
second. To lift more weight at the same rate, or the same weight more
quickly, you would need more horsepower".
ולחישוב של הספק הרנו :
735.5X182
------------- = כ-179 כ"ס בתקן DIN הגרמני
