• ###### amount of friction
• Friction sensitivity is an approximation of the amount of friction or rubbing a compound can withstand before prematurely exploding. (wikipedia.org)

• ###### rope
• An example of friction is when rope rubs against your hand and you get rope burn. (yourdictionary.com)
• In practice, the theoretical tension acting on the belt or rope calculated by the belt friction equation can be compared to the maximum tension the belt can support. (wikipedia.org)
• A friction burn may also be referred to as skinning, chafing, or a term named for the surface causing the burn such as rope burn, carpet burn or rug burn. (wikipedia.org)
• ###### fluid
• Skin friction is a component of drag , the force resisting the motion of a fluid across the surface of a body. (wikipedia.org)
• With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. (wikipedia.org)
• Friction loss is then the change in pressure Δp per unit length of pipe L Δ p L . {\displaystyle {\frac {\Delta p}{L}}.} When the pressure is expressed in terms of the equivalent height of a column of that fluid, as is common with water, the friction loss is expressed as S, the "head loss" per length of pipe, a dimensionless quantity also known as the hydraulic slope. (wikipedia.org)
• Friction loss, which is due to the shear stress between the pipe surface and the fluid flowing within, depends on the conditions of flow and the physical properties of the system. (wikipedia.org)
• The roughness of the pipe surface influences neither the fluid flow nor the friction loss. (wikipedia.org)
• ###### relatively
• The fact is that force is so fundamental that it defies full explanation, except in terms of the elements that compose it, and compared to force, friction is relatively easy to identify. (encyclopedia.com)

• In the limit of very high extrusion rates, the friction extrusion process closely mimics the conventional extrusion process with respect to strain levels. (wikipedia.org)
• ###### drag
• In astrophysics, dynamical friction or Chandrasekhar friction, sometimes called gravitational drag, is loss of momentum and kinetic energy of moving bodies through gravitational interactions with surrounding matter in space. (wikipedia.org)
