knee, ankle, hip and elbow
When doing jumping jacks, you primarily use your hip, knee, and shoulder joints. Your hip joints help with the leg movements, your knee joints assist in bending and straightening your legs, and your shoulder joints perform the arm movements.
Bones used in jumping jacks will be the bones of the arms and legs. The extremities will move when jumping jacks are done.
Jumping jacks can primarily place strain on the knees, ankles, and hips due to the repetitive jumping motion. Additionally, those who are not used to physical activity might also feel discomfort in their calves and lower back. Proper form and warm-up can help minimize discomfort in these areas.

Hinge joints are primarily used in sports that involve movements like bending and straightening, such as basketball, gymnastics, and weightlifting. In these sports, the elbow and knee joints act as hinge joints, allowing for a range of motion that facilitates actions like jumping, running, and lifting. The design of hinge joints provides stability and support during dynamic movements.

Other than to get your heart rate up and thus provide the same benefits as any aerobic exercise, they don't do much of anything. The jumping jack is an old and 'contrived' calisthenic exercise that used to be used for warming up. Although it may help loosen up the hips and shoulders, at least in the frontal plane (side to side movement) it is also an exercise that tends to interfere with coordination. Also it has a very small range of motion. Although it is a fairly efficient way to get the heart pumping, as an exercise it has no special efficacy or direct benefit.
During a jumping jack, the primary type of isometric contraction used is an isometric hold in the muscles that stabilize the body when landing. While jumping jacks primarily involve isotonic contractions for the upward and downward movements, the core and stabilizing muscles, such as the abdominals and glutes, may engage in isometric contractions to maintain balance and posture during the lateral arm and leg movements.
There are many various types of screw jacks and mechanical actuators. Examples include metal screw jacks, rotating screw jacks, inverted screw jacks and vertical screw jacks.
