  2. Nikon D50 - Wikipedia

    en.wikipedia.org/wiki/NIKON_D50

    The D50 is the only entry-level Nikon DSLR to have the autofocus motor ('screw drive') built into the camera body, making the camera backwards-compatible with mechanical-drive autofocus lenses (Nikkor AF/AF-D series) dating back to 1989. This feature has been eliminated on later entry-level models and is currently only available on mid-range ...

    To allow for turns, a person may either pick up or push down on the tail to raise either the nose wheel or tail wheel off the ground, then rotate the airplane by hand. A less cumbersome method involves attaching a short tow bar to either the nose wheel or tail wheel, which provides a solid handhold and leverage to steer with, as well as ...

    The AC-D50 AC adapter was also available, which attached to the rear of the D-50/D-5 and allowed it to be powered from AC input at 110, 120, 220, or 240 V, 50 or 60 Hz, 9 W with a DC output of up to 500 mA. The AC-D50 also offered line level audio out, presented as two RCA jacks. [citation needed]

    Though the vehicle was in mid-air, the spin created by the lightning bolt allowed it to reach 88 mph. Doc is trapped in 1885 and repairs were impossible because the time circuit control microchip, which governed the time circuits, was destroyed by the lightning bolt, and suitable replacement parts would not be invented until at least 1947.

    en.wikipedia.org/wiki/Rocker_arm

    Some OHC engines employ short rocker arms, also known as finger followers, [2] in which the cam lobe pushes downward on the back of the rocker arm to open the valve. In such a configuration one end of the follower is anchored (pivoting in place on a roller bearing), rather than having its fulcrum in the center like standard rocker arms.

    The Lancia D50 was a Formula One racing car designed by Vittorio Jano for Lancia in 1954. The car's design made use of many innovative features, such as the use of the engine as a stressed chassis member, the off-centre positioning of the engine to allow a lower overall height, and pannier fuel cells for better weight distribution and aerodynamics.

    As such, push-rod suspension systems allow for much greater high-speed stability, much lower levels of body-roll, and a much lower centre of gravity for the vehicle. [7] For pull-rod suspension systems, the only difference is the orientation of the rocker arms. In a push-rod system, the rocker arms are placed at the highest point in the assembly.
