The force on the wood by the crowbar causes an opposite force on the nail, which pulls it up. Since the force is not exactly up and down, there will be a component which forces it out in a curved fashion.

Speaking of only the forces, there will be compression under the head, shear in the head, tension in the shank, compression and shear along the shank.
The applied force to remove the nail is resisted by the friction force of the wood-nail interface.

Tension and shear. The force is no longer straight up as the bar cams around the curve of the claw.
