Balancing a Hammer: Explaining with Physics

[cragar]

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

 

[Astronuc]

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

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

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

 

[cragar]

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.
