A Gear

A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. - wikipedia

For the landscape photo, I should have use the smaller aperture to increase depth of view.  The camera should be on a tripod to reduce shaking.
