This is to allow movement between the deck of the bridge and its supports. The effect of thermal expansion or contraction will change the length of the deck and would cause bending or cracking of the supports if the deck was firmly attached.

∙ 11y agoBridges are designed for loads which are dynamic in nature. Specially the dynamic impact loading which occurs due to movement of vehicles. The rollers are put to make the structure flexible during such loading conditions.

∙ 10y agothe bridge has a roller at the end because as 6the bridge expands it would have no where to go so it would buckle or crush itself the roler is there with a slight gap , not big enough to notice but big enough for the roller to roll the bridged extra when expanded you annot feel this change when driving over it yet you can see it if u look at a picture from a hot day and one from a cooler one you an see that the bridge has expanded in both width and height!!!

A 3m longweightless beam is supported at each end by cables a painter 900N stands 1m from the left end what is the tension in each cable?
Tension in left side cable would be 600N and in the right side would be 300N.
6 Why is it a serious folly for a bungee jumper to use a steel cable rather than an elastic cord?
If you use a steel cable instead of a bungee cord to jump off a bridge, then you would hit the end of the cable at a greater impact than you would with something made of elastic which forces your back up at the end or point of impact. It is all about BOUNCING!
When do you hand in a term paper?

What is double end digits?

A physical property that is measure of the distance from one end of somethingto the other?
The measurement from one end of an object to the other end of the object is called the length of the object.
Why are some bridges supported by rolles at one side?
Thermal expansion and contraction can put huge stresses into a large structure such as a bridge. To minimise this effect, the rollers are designed to allow the end of the bridge to move with the expansion and contraction.
How does an abutment support an arch bridge?
the abutments at either end of the bridge anchor the arch so that it will not collapse, the weight of the arch is supported by the abutment on either end
What is the strength and weaknesses of cantilever bridge?
i think a strength is that it is made out of iron and that the weakness is that is only supported on one end of the bridge. yaaas
How is a cantilever bridge built?
The basic principle of a cantilever bridge is that the bridge is supported entirely at one end, the rest being held in place by steel pillars or beams.
When did Bay City Rollers end?
Bay City Rollers ended in 1983.
When did High Rollers end?
High Rollers ended on 1988-09-09.
Is cantileaver its own category of bridge or is it a sub category?
A cantilever is a structure supported at one end only, such as a diving board
Why are bridges placed on rollers?
when we have rollers at one end then it is allowed to expand freely without any thermal stress.in summers the bridges may expand due to the increase in the temperature and in winters the bridges may compress due to decrease in the temperature. the rollers help to increase/decrease the length of the bridge without any thermal stress. ----N.Doraditya
When did Bridge End railway station end?
Bridge End railway station ended in 1948.
Is the length and the span of a bridge are the same?
Probably not. Length would be the entire length to the point the road starts. The span would be the section with air under it. Depending on the design, there could be a fair amout of the bridge supported by dirt or concrete at either end.
When did The Bridge end?
The Atlantic Bridge ended in 2011.
When was Bridge End railway station created?
Bridge End railway station was created in 1881.
