The curved head frame holds the strings.
The head of a tennis racket is the entire section of the strings, and the part of the frame that surrounds the strings.
This depends on what you mean by "how many". If you mean how many individual pieces of string are used when stringing a racket the number would probably be one or two pieces. If by how many you wish to know the number of times the strings cross the head or the racket, the answer would vary by racket. The number of times the strings cross is called the "string pattern". To know this information you would have to look on the racket, probably around the throat and look for a number that looks something like "16x18" that means that there are 16 crosses and 18 mains. (Crosses span the narrower part of the head and can be described as running horizontally. The mains span the longer part of the head and are can be described as running vertically.)
The part that holds the slide in place on a microscope is called the stage. The stage is where you place your sample slide for viewing under the lens of the microscope.
There are three parts of a tennis racquet. The part that you hold is the "grip". Above the grip is the "neck". Someone who holds their tennis racket by the neck is said to be "choking" their racquet; this is not the correct way to play. The part that you hit the ball with (and the largest part of the racquet) is called the "head". The part makes up the head is the "rim". As for a badminton racquet, I would assume that it's very similar.

The strings are called Phloem Bundles (pronounced flom). They are part of the system that carries nutrition to all parts of the banana. Michael Thogersen
The wood part of a pencil is called the barrel or casing. It holds the graphite or lead core in place.
Badminton is a sport where the athlete's tool is his or her racket. Familiarity with the six main parts of the racket and their respective significance will improve the success of a badminton player.HandleStringed AreaThe athlete grips the racket with the handle. The handle is allowed to be attached to the wrist or hand for security purposes. HeadThe stringed area is the section with which the athlete hits the shuttlecock. The strings are flat and uniformly interlaced, and the area cannot be larger than 280 millimeters by 220 millimeters. ShaftThe head is the ovoid part of the racket that surrounds the stringed area and keeps it in place. ThroatThe shaft extends from the handle to connect it to the head, either with or without a further portion called the throat. FrameThe throat is a triangular extension of the shaft that further connects it to the head for extra support. Not every racket contains a throat.The handle, head, shaft, and throat (if present) combine to form the frame. It cannot be larger than 680 millimeters in length and 230 millimeters in width.
Yes, you can bring a tennis racket on a plane as part of your carry-on luggage, but it must meet the airline's size and weight restrictions for carry-on items.
