sliding friction उदाहरण वाक्य

उदाहरण वाक्य

1. :: : : The objective of the question is to determine the circumstances in which there is no sliding friction between the ball and the felt . " t " ) 13 : 28, 19 April 2010 ( UTC)
2. In some cars they may use a very aggressive launch similar to what you've described, but in most cars this would be counterproductive since static friction is generally greater than sliding friction and excess wheelspin gives you a sliding friction situation.

4. With an intensive triboelectrification facilitated by sliding friction, a periodic change in the contact area between two surfaces leads to a lateral separation of the charge centers, which creates a voltage drop for driving the flow of electrons in the external load.
5. In order to avoid misalignment, sticking and reduce sliding friction in bearing gearwheels engagements on adjacent end faces of their gearwheels and rollers, the teeth must be either made beveled and / or made with engagement by surfaces providing the efficient axial meshing.
6. Some escapements avoid sliding friction; examples include the grasshopper escapement of John Harrison in the 18th century, This may avoid the need for lubrication in the escapement ( though it does not obviate the requirement for lubrication of other parts of the gear train ).
7. More recently in San Francisco, the renovation of 680 Folsom Street, a fourteen-story 1960s steel building, inspired an ultra-modern iteration of the shinbashira : an 8-million-pound structural concrete core that can freely pivot atop a single sliding friction-pendulum bearing during a large earthquake.
8. In practice, static friction tends to be marginally greater than sliding friction so in the last millisecond there may be a slight jerk and a coming to rest marginally before the calculated 40.8 m ( I just used v 2 = 2as with " a " as you calculated-simplified from Equations of motion ).
