Static friction between two surfaces
Prevents the relative motion between them
Opposite to the direction of motion of them
Acts in opposite direction of applied force
Both $(a)$ and $(b)$
(a)
Maximum value of static friction is called
A heavy uniform chain lies on a horizontal table-top. If the coefficient of friction between the chain and table surface is $0.25$, then the maximum fraction of length of the chain, that can hang over one edge of the table is …… $\%$
Figure shows a man standing stationary with respect to a horizontal conveyor belt that is accelerating with $1\; m s^{-2}$. What is the net force on the man? If the coefficient of static friction between the man’s shoes and the belt is $0.2$, up to what acceleration of the belt can the man continue to be stationary relative to the belt? (Mass of the man $= 65 \;kg.)$
Why coefficient friction is considered as static friction ?
Confusing about what to choose? Our team will schedule a demo shortly.
