What are the strongest joints in a balsa bridge?
it is a flat joint
What are the two types of joints in construction?
Expansion joints. Butt,lap,half-housed,mortise/tenon and mitre joints to name some common ones.
What are the Processes and operations involved in making rubber expansion joints?

What is application of expansion joint?
Expansion joints include: PTFE expansion joint, Rubber expansion joint, Metallic expansion joint, and Fabric expansion joint. visit website: www.rubbersealing.comPTFE expansion jointThe PTFE expansion joints are unreinforced PTFE that come standard with iron 150# drill flanges. Stainless flanges are available. They are avaialable in 2, 3, or 5convolutions of varing movements. The 2-convolution joint is sometimes referred to as a "coupling".Molded flexible couplings and expansion joints of PTFEdesigned to help protect pumps, compressors and other expensive equipment.Bellows-type flexible couplings and expansion joints are contour molded of black PTFE by a patented process. They are corrosion resistant, non-aging, with extraordinary flex life and unmatched reliability. These superior units cost no more than those made of lesser materials. The flexible element is formed over the full sealing face of the end flanges eliminating troublesome separate gaskets.Note the change in pressure rating with
What is thermal expansion and how bridge roads and sidewalks compensate or deal with thermal expansion?
Thermal expansion (TE) is a process in which materials expand due to changes in temperature. How different structures deal with or compensate thermal expansion (just some examples): Bridges and other structures have expansion joints (there are gaps in the road, which you hear/feel when crossing them in a car for example - usually in both ends of the bridge and sometimes in between as well, depending on the lenght of the bridge). Sidewalks - depends on the material of the sidewalk (sometimes there may be some spaces between different sections, but the temperature fluctuations are not so huge that it is reasonable to use any predicament against TE. Railroads - do you know the banging sound really associated with trains and railroad? This is a basic example of thermal expansion compensation. The tracks are assembled so that the ends of two track sections are not touching each other. The gap in between allows the track to expand in heat (therefore the sound of train wheels rattling is louder in the winter when the gaps are bigger and less in the summer)
What happens to a bridge's expansion joints on a hot day?
If there is no expansion joints on a bridge and if it's really hot the molecules of the bridge will be separated slowly and the bridge will collapse
Why are there joints in bridges?
The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.
Explain the purpose of an expansion joint on a bridge?
The purpose of an expansion joint on a bridge it to permit the components to expand and contract with changing temperatures without stressing the entire bridge structure. Early bridge failure would be the result of building a modern bridge without expansion joints.
What type of bridge is the sunshine skyway bridge?
Cable stay. Yes, this is a cable stayed bridge. I actually sold the expansion joints (Waboflex SR4) for this bridge! It is a very impressive bridge.
What are bridge joints?
joints on a bridge
Why do engieneers add expansion joints to a bridge in order to make them safer?
The joints are essential to maintain the structural integrity of the bridges components throughout temperature ranges. Heat expands the structures and cold contracts. Without expansion joints the bridges overall life would be greatly reduced and cracks and tears could rapidly develop, making the bridge less safe.
What has the author W Black written?
W. Black has written: 'Horizontal forces on bridge expansion joints due to vehicles'
Expansion joints are used in bridges in order to prevent the bridge from?
Buckling; shriveling, bending, or curling from heating or pressure. (heating, in this case)
What is an expansion bridge?
bridge expansion is when one side of the bridge needs to be propped up
Why do engineers design bridges with expansion slotsions?
Because bridges expand and contract with the change in temperature. The expansion joints allow the bridge to 'flex' as the temoerature rises and falls, ensuring the structure doesn't buckle or collapse.
Does concrete expand?
yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome
