Joints are only necessary if your body has a skeleton or an exoskeleton. Worms and snails get by nicely without joints, as do many fish.
Examples of rigid joints in the human body include sutures in the skull, where bones are tightly fused together with very little movement possible. Additionally, synarthroses joints, such as the joints between the teeth and mandible, are also considered rigid because they do not allow for significant movement.
No, joints are not the fulcrum of a lever. Joints are points in the body where two or more bones meet and allow movement. A fulcrum is the fixed point around which a lever pivots in order to create mechanical advantage.
The number of joints you can make with a gram of weed depends on how much you use in each joint. On average, you can typically roll 2-4 joints with a gram of weed.
The method of sections involves cutting through a structure to analyze specific sections for forces and stresses, while the method of joints analyzes the forces at individual joints in a structure to determine overall stability and strength.
Reducing friction at movable joints helps to improve movement efficiency, reduce wear and tear on the joint surfaces, and decrease the risk of injuries such as strains and sprains. This is especially important for athletes and individuals involved in physical activities that place repeated stress on the joints.
Otherwise you could not move
Joints are important because they provide mobility to the human body. Without joints our body would have been like a statue.
TKY weld joints are tubular joints used for welding. They are expressly used for when fabrication of a structure is necessary.
To avoid bone-on-bone friction.
not necessary....most of the bones in our body DO have joints like the femur and tibia.....but some dont for example the bones that make up our skull...etc.
Joints are necessary for mobility and flexibility in our bodies. They allow bones to move in relation to each other and aid in performing various movements like walking, running, and bending. Joints also provide stability and reduce friction during movement.
The maximum size for a concrete slab without needing expansion joints is typically around 100 to 150 feet in either direction. Beyond this size, expansion joints are usually necessary to prevent cracking due to temperature changes and shrinkage.
Correctly phasing the u joints will prevent driveling vibration Doing it incorrectly can cause a damaging vibration that can ruin, transmission, transfer case, differential etc.
The effect of changing velocity can be eliminated by phasin the hookes joint Akray
the different groups of joints in the body are saddle joints gliding joints hinge joints and ball and socket joints .
The 1998 Dodge Dakota has both upper and lower ball joints. OEM grade replacements are approximately 40-50$ per ball joint (as of August 2014). Labor to replace will depend on how many need replacement and time necessary. The changing of ball joints will require an alignment upon completion additionally. It is advisable to replace ball joints as pairs, when possible.
Yes.... the main one would be the joints between your jaw (mandible) and your skull - the temporomandibular joint (or TMJ) for short. You couldn't talk without breathing so joints involved in this will include all the joints between the thoracic spine and the ribs, the ribs and the sternum and the sternum and the clavicles.
