Main Question or Discussion Point

this is not a home work question k i know that it is easier to balance a hammer by having your finger touching the handle and the claw part of the hammer away from the earth
but how can we explain this with the laws of physics i know it has something to do with center of mass and inertia

The hammer is subject to its weight, W, which is the force due to its mass and acceleration of gravity m[tex]\vec{g}[/tex].

In order to achieve zero torque, τ = [tex]\vec{r} x \vec{W}[/tex], |r| must be zero.

What must be the relationship of the center of mass with the pivot point, for a hammer to be balanced?

the center of mass is closer to the head of the hammer so it is easier to stabilize
what do u mean by pivot point. if i think i know what u mean by pivot point
u want the pivot point farther from the center of mass.
