  2. Minimum railway curve radius - Wikipedia

    en.wikipedia.org/wiki/Minimum_railway_curve_radius

    High Speed 1 (section 2) in the UK has a minimum vertical curve radius of 10,000 m (32,808 ft) [6] and High Speed 2, with the higher speed of 400 km/h (250 mph), stipulates much larger 56,000 m (183,727 ft) radii. [7] In both these cases the experienced change in weight is less than 7%.

    Factorio is a construction and management simulation game developed and published by Czech studio Wube Software. The game was announced via an Indiegogo crowdfunding campaign in 2013 and released for Windows , macOS , and Linux on 14 August 2020 following an early access phase, which was made available on 25 February 2016.

  5. Speeds and feeds - Wikipedia

    en.wikipedia.org/wiki/Speeds_and_feeds

    Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

  6. Thermal velocity - Wikipedia

    en.wikipedia.org/wiki/Thermal_velocity

    Thermal velocity or thermal speed is a typical velocity of the thermal motion of particles that make up a gas, liquid, etc. Thus, indirectly, thermal velocity is a measure of temperature. Technically speaking, it is a measure of the width of the peak in the Maxwell–Boltzmann particle velocity distribution

    en.wikipedia.org/wiki/Linear-feedback_shift_register

    A Fibonacci 31 bit linear feedback shift register with taps at positions 28 and 31 (indicated by the yellow LEDs), giving it a maximum cycle and period at this speed of approximately 8 years. The bit positions that affect the next state are called the taps. In the diagram the taps are [16,14,13,11].
