EP Museum: Stanley Steamer exhibit

[@trenthall1427]

Dad.. listening to your voice is hard and great at the same time.. miss you.

[@223mike]

is there any drawings available?

[@sourabhquestionpaper1260]

What is the size of piston ❓

[@tomcat8316]

IF ? Stanley had a " flash " boiler it would have over taken gasoline powered auto's !

Great car and generally great info. But 20HP at 1 RPM would require 105769 ftlb of torque. 1 HP = 550 ft-lb / sec. 20 HP 11000 ftlb/sec. 24" tire at 1 RPM = 6.2831856 ft/min, 0.10471976 feet/sec. A Stanley engine would rip it's self apart.

yeet!

I was wondering how a 1900s Stanley set the land speed record of over 127 mph with your figures ...

1 horse power is 550 pounds to one foot per second. It is a calculation of how much work is being done. And the calculation is literarily how much weight you can lift one foot in a second in a pulley system. A damn garage door motor has between 1/2 to 2 HP depending on model. Also you are mixing speed and force. A 20 HP engine exerts 11000 pounds of force at the point of rotation AND its is a theoretical number that says if you get up to speed of 1ft per second the engine should be able to pull 11000 pounds. that is a speed of 39mph, which means this engine exerts the most power, since I do not know the exact specs, but a 10 inch diameter crank shaft rotating about 30rpm with a power of 20 HP (and since you have about 90~% efficiency with steam) would just about be able to pull just shy of 10,000 pounds 1 feet of the ground in one second. This of course would snap any rope you would use or mangle the axle/crank shaft if you went from stop to full speed immediately. (as far as I know) But since steam is a gas it compresses within the cylinders a bit. It is why these cars have somewhat smooth if immediate acceleration, since physics, like weight and momentum and stuff makes it impossible... and also why these engines needs to be emptied on water when you start firing these cars up... cause water has zero give, and does break the pistons/cylinders if left in there. So if it had been a water engine instead of a steam engine, yes it would have ripped itself apart.
