At 2,500 pounds (1.1 t), the 9N could plow more than 12 acres (4.9 hectares) in a normal day pulling two 14-inch (360 mm) plows, [3] outperforming the tractive performance of the heavier and more expensive Farmall F-30 model. [3]
ISO 500-2 Narrow-track tractors, dimensions for master shield and clearance zone; ISO 500-3 Main PTO dimensions and spline dimensions, location of PTO. The original type (designated as Type 1) calls for operation at 540 revolutions per minute (rpm). A shaft that rotates at 540 rpm has six splines on it, and a diameter of 1 + 3 ⁄ 8 inches (35 ...
the rear of the F135 engine (nozzle rotated down) that powers the Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift ...
The bore and stroke of the engine both measure 86 mm (3.39 in), which engineers refer to as square. According to Mitsubishi, the new cylinder dimensions contribute to a free-revving character (max power at 6500 rpm), linear power delivery and wide torque curve.
A simple dumbwaiter is a movable frame in a shaft, dropped by a rope on a pulley, guided by rails; most dumbwaiters have a shaft, cart, and capacity smaller than those of passenger elevators, usually 45 to 450 kg (100 to 992 lbs.) [2] Before electric motors were added in the 1920s, dumbwaiters were controlled manually by ropes on pulleys. [1]
