A typical sportbike might have a rake as steep as 25 degrees, while a chopper may be closer to 45 degrees. A touring bike is typically at around 29 degrees and a cruiser at 32. More rake does two things: one, it makes the wheelbase longer, and two, it generally increases a motorcycleâs trail. Trail (B) is measured in distance (inches or millimeters) between the point of the front wheelâs contact with the ground and a line drawn through the axis of the steering head.
Reed Instruments About Reeds A reed is a thin elastic strip of cane fixed at one end and free at the other. It is set into vibration by moving air. Reeds are the sound generators in the instruments described below.Cane reeds are built as either double or single reeds. A double reed consists of two pieces of cane carved and bound into a hollow, round shape at one end and flattened out and shaved thin at the other. The two pieces are tied together to form an channel. The single reed is a piece of cane shaved at one end and fastened at the other to a mouthpiece. Single Reed InstrumentsClarinet: A family of single reed instruments with mainly a cylindrical bore. They are made of grenadilla (African blackwood) or ebonite, plastic, and metal.

The term tuba is applied rather loosely to any low-pitched brass instrument other than the trombone; such instruments vary in size, and are known by various names. The contrabass tuba, which is most common, plays in the same range as the double bass. The helicon and sousaphone are contrabass tubas used in marching bands; they coil around the player and rest on the left shoulder. The baritone and euphonium are small tubas, mainly band instruments, pitched the same as the trombone.
