  2. Rocker-bogie - Wikipedia

    en.wikipedia.org/wiki/Rocker-bogie

    A rocker bogie In motion - incorrectly shows chassis staying level; the chassis actually maintains the average of the two rockers Rocker bogie on Curiosity. The rocker-bogie system is the suspension arrangement developed in 1988 for use in NASA's Mars rover Sojourner, [1] [2] [3] and which has since become NASA's favored design for rovers. [4]

  4. Four-bar linkage - Wikipedia

    en.wikipedia.org/wiki/Four-bar_linkage

    Some mechanisms that produce reciprocating, or repeating, motion are designed to produce symmetrical motion. That is, the forward stroke of the machine moves at the same pace as the return stroke. These mechanisms, which are often referred to as in-line design, usually do work in both directions, as they exert the same force in both directions. [6]

  5. Lateral motion device - Wikipedia

    en.wikipedia.org/wiki/Lateral_motion_device

    The Southern Pacific class 5000 4-10-2 employed a conventional leading bogie but used lateral motion devices on the leading driven axle to reduce the rigid wheelbase. [4] Their GS-4 class 4-8-4 also did and employed springs to control the lateral motion, thereby assisting the bogie in easing the engine into curves. [ 5 ]

  6. Tsiolkovsky rocket equation - Wikipedia

    en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

    A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...

  7. Adams axle - Wikipedia

    en.wikipedia.org/wiki/Adams_Axle

    In 1865 the Society of Engineers, London, made direct comparison between the radial axle, invented by William Bridges Adams, and a bogie design with an india-rubber central bearing invented by William Adams: during trials on the North London Railway the laterally sprung bogie was thought superior to the radial axle, [2] but when William Adams moved from the NLR to the London and South Western ...

  8. Gab valve gear - Wikipedia

    en.wikipedia.org/wiki/Gab_valve_gear

    The hooked rod from the right is driven by the eccentric. When engaged, it rocks the valve arbor, the square shaft, back and forth. Bellcranks behind the shaft work the valves via the vertical pullrods. Gab valve gear was an early form of valve gear used on steam engines. Its simplest form allowed an engine to be stopped and started.
