  2. Parking pawl - Wikipedia

    en.wikipedia.org/wiki/Parking_pawl

    The main components of a parking pawl mechanism are the parking gear, parking pawl, actuator rod, cam collar, cam plate, pivot pin, and parking pawl return spring. The mechanism assembly is designed so that the parking pawl tooth collides and overrides the parking gear teeth (ratchets) until a safe engagement speed for the vehicle is reached.

  3. Terraria - Wikipedia

    en.wikipedia.org/wiki/Terraria

    Terraria (/ t ə ˈ r ɛər i ə / ⓘ tə-RAIR-ee-ə [1]) is a 2011 action-adventure sandbox game developed by Re-Logic. The game was first released for Windows and has since been ported to other PC and console platforms.

  4. 2007 Bombardier Dash 8 landing gear accidents - Wikipedia

    en.wikipedia.org/wiki/2007_Bombardier_Dash_8...

    An investigation into the cause of the failure to deploy revealed that the right main gear hydraulic actuator eyebolt had broken away from the actuator. A further analysis of the actuator showed corrosion of the threads on both the inside threads of the piston rod and the outside threads of the rod end, leading to reduced mechanical strength of ...

  5. Actuator - Wikipedia

    en.wikipedia.org/wiki/Actuator

    An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. [1] An actuator translates such an input signal into the required form of mechanical energy.

  6. Ball screw - Wikipedia

    en.wikipedia.org/wiki/Ball_screw

    A ball screw (or ballscrew) is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction.

  7. Solenoid (engineering) - Wikipedia

    en.wikipedia.org/wiki/Solenoid_(engineering)

    Two rotary actuators on opposite ends of the rotary snap-switch shaft, can advance or reverse the switch position. The rotary solenoid has a similar appearance to a linear solenoid, except that the armature core is mounted in the center of a large flat disk, with three inclined raceways coined into the underside of the disk.

  8. Rotary actuator - Wikipedia

    en.wikipedia.org/wiki/Rotary_actuator

    A rotary actuator is an actuator that produces a rotary motion or torque. The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators are electrically powered; others may be powered pneumatically or hydraulically , or use energy stored in springs .

  9. Tyndall's bar breaker - Wikipedia

    en.wikipedia.org/wiki/Tyndall's_bar_breaker

    The bar breaker experiment comprises a very rigid frame (d) and a massive connecting rod (b). The rod is held on one side by a cast iron bar (c) that is going to be broken in the experiment and, at the other end, by a nut (a) that is used to compensate the thermal expansion. [3]
