Where are all the horses indeed.
well lets just line up 120 horses and connect them to a chevy s10 truck and see which one has more power.
I say the 120 horses would win a tug of war between the two.
even though the chevy has 120 horses of power.
550 ft lbs * 120 horses = 66,000 lbs of horse torque.
can the chevy truck with 120 H.P. lift 66,000 lbs to a height of 1 ft in 1 second?
NO...NO...NO...NO.
can the 120 horses lift 66000 lbs to a height of 1 ft in 1 second?
YES...YES...YES...YES.
if James Watt were alive today
and he needed to "lift" 66,000 lbs 1 ft in 1 second
and he bought a 120 H.P. chevy s10 truck to do the job with.
he would be greatly dissapointed.
he might find it usefull to move himself and a passenger to get to the place where the 120 horses are being used to lift the 66,000 lbs.
Is there a horse that can lift 33,000 pounds or even 1100 pounds?
YES..
1100 lbs can be lifted by 1 horse using a 2-1 gear ratio.
33,000 lbs can be lifted by 1 horse using a 60 - 1 gear ratio.
because the force that a horse can deliver to a mechanical advantage is 550 lbf.
a chevy s10 truck can only deliver a 140 lbf to a
mechanical advantage.
Would you say that a horse has 39.2 times the amount of torque as an S10 truck?
No , I said that a horse has 3.92 times the amount of torque that a chevy s10 has.
550 / 140 = 3.92
550 ft lbs of torque is a twisting force that can supply 550
pounds of force at a 1 ft radius.
if you use the 550 lb force at a radius of 1 foot
then you can get 550 pounds of force.
if you use the 550 lb force at a radius of 2 feet
then you can get 275 pounds of force.
the chevy s10 truck developes a maximum of 140 ft lbs of torque
@ 3600 rpm. 60 rps.
in the chevy s10 truck if the distance from the center of the wheel to the tire tread is exactly 12 inches and we know the max available torque is 140 ft lbs @ 3600 rpm , the gear ratio of the truck in order to lift a 66,000 lb weight would need to be 471 - 1
and that would only work if the truck weighs more than 66,000 lbs because of friction between the road and the tire.
as for horses a 3,000 lb truck no matter how many horse power it has can easily be dragged around by 6 horses.
even if the brakes are locked down.
the only resistance to the truck moving would be the friction between the road and the tires.
so once the horses begin to move the truck , you could remove 4 or 5 of the 6 and still drag it around.
