Degrees of freedom (mechanics) pose, but at any point, you can move it only by a forward motion and a steering angle. So it has two control DOFs and three representational DOFs; i.e. it is non-holonomic. A fixed-wing aircraft, with 3–4 control DOFs (forward motion, roll, pitch, and to a limited extent, yaw) in a 3-D space, is also non-holonomic, as it cannot move directly up/down or left/right. A summary of formulas and methods for computing the degrees-of-freedom in mechanical systems has been given by Pennestri, Cavacece, and Vita. In electrical engineering "degrees of freedom" is often used to describe the number of directions
Silk Degrees "hit the R&B charts in a big way with the addictive, sly "Lowdown" [...] and expressed his love of smooth soul music almost as well on the appealing "What Can I Say."" However, Henderson stated that "Scaggs was essentially a pop/rocker, and in that area he has a considerable amount of fun." He concluded: "Though not remarkable, the ballads have more heart than most of the bland material dominating that format." On February 27, 2007, "Silk Degrees" was reissued by Legacy Records with three bonus tracks recorded live at the Greek Theatre on August 15, 1976. Silk Degrees Silk Degrees
