Friction Forces

Some articles on friction, friction forces, forces, friction force:

Engine Efficiency - Friction
... An engine has many moving parts that produce friction ... Some of these friction forces remain constant (as long as applied load is constant) some of these friction losses increase as engine speed increases, such as piston side forces and connecting bearing ... A few friction forces decrease at higher speed, such as the friction force on the cam's lobes used to operate the inlet and outlet valves (the valves' inertia at high speed tends to pull the cam follower away from ...
Slip-critical Joint
... from structural engineering, is a type of bolted structural steel connection which relies on friction between the two connected elements rather than bolt shear or bolt ... slip-critical connection, loads are transferred from one element to another through friction forces developed between the faying surfaces of the connection ... These friction forces are generated by the extreme tightness of the structural bolts holding the connection together ...

Famous quotes containing the words forces and/or friction:

    What if all the forces of society were bent upon developing [poor] children? What if society’s business were making people instead of profits? How much of their creative beauty of spirit would remain unquenched through the years? How much of this responsiveness would follow them through life?
    Mary Heaton Vorse (1874–1966)

    The admission of Oriental immigrants who cannot be amalgamated with our people has been made the subject either of prohibitory clauses in our treaties and statutes or of strict administrative regulations secured by diplomatic negotiations. I sincerely hope that we may continue to minimize the evils likely to arise from such immigration without unnecessary friction and by mutual concessions between self-respecting governments.
    William Howard Taft (1857–1930)
