Is this setup a physical pendulum?

[regisz90]

I have to calculate the small oscillations around the equibrillum position. My question is only that is this a physics pendulum so i can use the formula T=2$\pi$$\sqrt{\Theta/mgd}$ , where d is the distance of the mass centre and the pivot and $\Theta$ is the moment of inertia of the pendulum about the pivot point.
So is this a physics pendulum?
Thx for help

The question I think you really want to be asking is, "Is this a PHYSICAL pendulum?" The difference is the word "physical" in place of "physics."

Rather than ask that, why don't you simply write out the equation of motion for this system, starting with F = m a for this system, and find out if it comes down to that formula? That would be a lot more interesting and useful.
