    The example above shows an explosive with a compatibility group "A" (shown as 1.1A). The actual letter shown would depend on the specific properties of the substance being transported. For example, the Canadian Transportation of Dangerous Goods Regulations provides a description of compatibility groups. 1.1 Explosives with a mass explosion hazard

  4. Friction - Wikipedia

    en.wikipedia.org/wiki/Friction

    Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. [7] [8] Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. [9] [10] [11] Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.

  8. Oil additive - Wikipedia

    en.wikipedia.org/wiki/Oil_additive

    Friction modifiers or friction reducers, like molybdenum disulfide, are used for increasing engine fuel economy by reducing friction between moving parts. [6] Friction modifiers alter the lubricity of the base oil. Whale oil was used historically. [7] In [8] it's shown how use of anti-friction additives can increase the power efficiency of a motor.
