on what factor does the maximum or limiting value of contact forces depend.What happens if this limit is exceeded
Asked by bhavna | 8th Apr, 2012, 03:01: PM
Limiting value of contact force is given by
Where m = mass of block
g =acceleration due to gravity
? = coefficient of friction.
So, contact force depends on mass of block, coefficient of friction(roughness of material).
If this limit is exceeded then there is need of more force to move the object.
