The coefficient of static friction may be

We know that coefficient of static friction

${\text{μ}}_{\text{s}}=\frac{{\text{f}}_{\text{ms}}}{\text{N}}$

${\text{μ}}_{\text{s}}$  depends on nature of two surfaces in contact.

So we get ${\text{f}}_{\text{ms}}<\text{N}\left(\text{or}\right){\text{f}}_{\text{ms}}=\text{N}\left(\text{or}\right){\text{f}}_{\text{ms}}>\text{N}$

Therefore ${\text{μ}}_{\text{s}}$  can be greater than 1 or less than 1 or equal to 1.
