Totally important! The connections must be well made and the wires tightly joined to prevent a loss of voltage to the device powered. In high current situations a poor connect…ion causes heat at the connection and oxididaion of the wires and no more or intermittent connections. Most problems in electrical is not a short but: an open connection. Additional Answer In the case of high-voltage underground cables, the restoration of the insulation is critically important, as is restoring the cable's waterproof integrity. The skills required are such that cable jointers serve a full apprenticeship in that particular trade.
To be able to move our body... Like the knee, elbow, etc
Immovable joints in the skull would affect the brain. If the brain moved around due to these immovable parts, then people would have brain damage.
what is importance of joint stock company
It provides a way for politicians to more easily screw over our country, no matter what stupid, idiotic idea one member comes up with, the others can help make it more stupid …and idiotic. Then when the American people find out they've been screwed, the politicians can point at other members of the committee and blame them and keep getting re-elected by the more than stupid and idiotic American voters. (Well, at least the majority of them.)

Jointed limbs are important to arthropods to facilitate survival through mobility, feeding, sensory functions, respiration, etc. The reason for the jointing itself can be …attributed to the composition of the exoskeleton (chitin); because of its rigidity, jointing is necessary to provide degrees of freedom for rotation, flexion and extension, etc., to perform physical functions; without jointing, they might be immobile. Other animal phyla might appear to have obviated the use of limbs altogether (like the annelid earthworm) or utilize an unjointed muscular limb (like cephalopod molluscs).
Because it absorbs the impact of the motion of your joints
Yes, they are because that's how we can bend our elbows, hands, knees, neck, and other parts of body contaning joints.
A good reason for expansion joints is that they allow for a rise and fall of temperature. If they were not implemented in bridges or building, the intense heat in the summ…er would expand the metal, brick, or concrete materials in a structure and the structure would have cracks and breaks in it. Also, in the winter the harsh cold temperatures would make the materials to contract (come together) and this would also result in disasterous circumstances. All matter's molecules (or all molecules I have heard of) will speed up at higher temperature and slow down at lower temperatures. This is the reason for expansion joints in the first place... too allow expansion without breaking at extreme high and low temperatures. Alternate Answer: They are usually used to accomodate changes in temperature. So if the temperature changes and causes problems or destruction, then the expansion joints are very important, or most important. Have you driven on a poorly designed road in winter where every 100 feet or so there is a heavy bump? Improper design. One road near here has water frozen below the joint or crack area and it causes little humps in the road. They totally ruin the ride quality of the road. Have you had a windshield on a car crack because of cold? When making a wood floor in a house an expansion area is allowed around the floor so it will not buckle or damage the wall. When I was young the school gymnasium would buckle when it was wet. They replaced the whole gymnasium. I designed a fix for a restraunt where the concrete floor was heaving up and down 6 inches, and breaking up the floor, each spring during the thaw when water could get under the foundation. In this case, I rerouted the water under the building so it could build up no pressure under the restraunt. The normal expansion joints for temperature only were fine. This expansion was due to water pressure under the building. The building had worked fine for 20 years until the water flow beneath it changed due to construction further up the hill and increased run-off. Alternate Answer again: An expansion joint is an assembly designed to absorb the stresses produced by the heat and cold atmospheric conditions to the construction materials. The purpose is to hold the whole assembly intact and provide security. Normally large structures like flyovers, stadiums, auditoriums, swimming pools, large buildings have very high impact of summer heat and that leads to expand the construction materials contracting. In the long run, this makes it more vulnerable to cracks. A similar phenomenon happens in the winter and again it makes more vulnerable and affects the life of the structures. Therefore expansion is mandatory to such buildings and large structures. Ref.:architecture.answers.com/equipment/expansion-joint-filler-boards-and-its-importance
That is a tough question because, essentially, they are all important. If I had to pick just one, and only one, I would pick the pubic symphysis. It is the joint made of fibro…cartilage that is between the two pubic bones. It becomes soft and elastic just before a woman gives birth to her baby. If it does not allow the pubic bones to open up, then the delivery of the baby would be hindered. So, I would say it is the most important joint because many of us would not be here today if it did not work properly.
You should have phrased it, "What is the importance of the joints in the skeletal system?" Well you use joints all the time if you don't know that... I will give you an exampl…e of why it's so important. If you only had bones without any joints. You would not be able to bend, or twist. You would be EXTREMELY stiff. It would probably be nearly impossible for you to move. Also you would not be able to play Video Games because you have to bend your fingers or twist and rotate them.
so that you are able to move fingers. for example: playing instruments, typing, texting, etc.
to prolong live and it will take less force to get it moving
because without stocking up on joints, companies tend to get cranky
