Rhino UTV Rolls at Low Speeds

The calculations have shown that the theoretical rollover for a Rhino 450 with occupants is 12.23 miles per hours.

Center of Gravity on the Rhino 450 (with occupants) = [(32.77 inches * 1049 pounds) + (43.55 inches * 180 pounds) + (43.10 inches * 130 pounds)]/(1049 + 180 + 130 pounds) = 35.185 inches

Using this new value of the height of the center of gravity for the UTV and occupants:

Velocity for overturn = [((153.5/12)*32.2*(27.5/12))/(35.185/12)] .5

= 17.94 ft./second = 12.23 miles/hour *
