i want to know about expansion joints?

They are used to prevent cracking and tearing of various types of materials due to expansion and contraction of said materials because of temperature changes. What else do you need to know?

Grinding up materials between the gears (i.e. a paper shredder)\n\nAny transfer of motion in a device which, by design, dictates that the energy exerted be moved to a different, more practical location (i.e. a series of ceiling fans connected to one another or a locking system in a safe)\n\nReinforcement and/or stablization of movement needed for accuarcy purposes or to prevent slipage/overspin (i.e. a clock or analog stopwatch).

Don't rotate your joints like that.

They can expand to whatever size is needed.\nThey can even have babies come out through them!

Contraction means it gets smaller, more condensed.  Expansion means it gets larger, less dense.  It usually, but not always, is a function of temperature.  Things generally contract when they get cold and expand when they get hot, due to the amount of space in between the molecules when they are moving faster when they are heated.

Bridge bolts hell yeah Its not a company name though its a product Ive got some on me 10 year old board they are the shnizle what they do is replace your screws that hold the trucks on.  Vibration from riding causes the screws to come loose well these bridge across two holes so you need four bridge bolts per board.  you can tighten the crap out of them and they wont pull through your board and also the dont get all stripped out like screws do and you never need a screw driver just a wrench.  I think I ordered the from California Cheap Skates back in the day I dont know if they still have them or not.  If you can get them you should you will love them, definately worth looking into. Good Luck   Oh yeah Grind king trucks are cool to in stead of a long bolt and nut stiking out on your king pin its reverse and uses a hex wrench they dont hank up as mush and you can grind alot faster and farther.

To allow positive and negative motion so that you can bend the elbow or the leg.  Gotta have one to push and one to pull it back.

First of all you would find the first part of you question in the manual. The second part is documented in the Manual of STEEL CONSTRUCTION "Allowable Stress Design" Ninth Edition. and the third part is called an M.T.R. This is the birth compasition of the metal used to make the beam which gives you the carbon hardness and rating of that beam. \nGood luck,\nChris

You can buy this...\n\nhttp://www.cabelas.com/cabelas/en/templates/product/standard-item.jsp?_DARGS=/cabelas/en/common/catalog/item-link.jsp_A&_DAV=MainCatcat20712&id=0012783224318a&navCount=2&podId=0012783&parentId=cat20803&navAction=push&catalogCode=IG&rid=&parentType=index&indexId=cat20803&hasJS=true\n\nor just the hammer.  That's what I did and the pull is about 2lbs and smooth.

Systematic joints - rough planar geometry, regular parallel orientations, regular spacing\n\nNonsystematic joints - curved, irregular in geometry, always terminate against older joints which commonly belong to a systematic set\n\nCross joints - systematic joints of one set consistently terminate against the joints of another set\n\nOblique / diagonal joints - joints that cut a fold or some other linear feature at high angles\n\nSheet joints / Exfoliation joints - curved extension fractures that are subparallel to the topography and result in a characteristic smooth, rounded topography, may be found in many kinds of rocks but they are best displayed in plutonic rocks in mountainous regions where the sheets resemble layers of an onion\n\nColumnar Joints - extension fractures characteristic of shallow tabular igneous intrusions, dikes, sills, or thick extrusive flows; fractures separate the rock into roughly hexagonal or pentagonal columns which are often oriented perpendicular to the contact of the igneous body with the surrounding rock

it all depends on where the joints are to help the flimsy outer parts to grow and grow flimsy now if you put a fan on it and let it blow on it very light wind the flimsy parts will get stronger.

Ask a specialist or a person whose job is to do such things.\nSorry, but I do not believe anyone here can be precise.

Go for a wooden one that can be extended. Usually, the back third can be replaced by an extention that you use when using the rest. Avoid gimmick cues like aluminium and carbon fibre. Leave those to the fishermen!
