Sweet deal!! Is that 18" to top of cushion? How did you mount seats?
I did some math that I am pretty sure is correct:
The center of gravity of people sitting in those seats is about 4 feet above the wheel hub.
Assume you got two, 225 pound guys strapped in for a total of 450 pounds or 204 Kg.
Also assume you make a tight turn at only 15 mph or 6.7 meters per second. The Viking turning radius is about 178" or 4.5 meters.
Acceleration = velocity ^2 / radius = (6.7 * 6.7) / 4.5 = 10 meters per second ^2.
Force = mass * acceleration = 204 Kg * 10 m/s ^2 = 2040 Newtons = 460 pounds.
Torque applied at hub height = 4 feet * 460 pounds = 1840 foot pounds! That is a lot of torque!
lol, nice.Yup, over 35 years ago though.
That's why I am bad. A good monkey wouldn't give you a headache.damn it BadM0nkey....that made my head hurt!
