Question

write the relation between stakic
friction and normal reaction ?​

Answer 1

Answer:

The Laws of Static Friction are:

The magnitude of limiting friction is independent of area and shape of surfaces in contact as long as the normal reaction remains the same. iii. The magnitude of limiting friction 'F' is directly proportional to normal reaction 'R' between the two surfaces in contact.

Explanation:

Hope u understand the answer: )

Answer 2

For Any surface, if its Coefficient of Static Friction is:

$\sf coefficient \: of \: friction = \mu_{s}$

Then, The value of static Frictional force acted upon any body on the suface is Given by:

$\sf f _{s} = \mu_{s}N$

$\implies \sf N = \frac{f_{s}}{ \mu_{s}}$

is the required relation
