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.
Tension in left side cable would be 600N and in the right side would be 300N.
A summary at the end of an experiment is typically called a "conclusion." This section synthesizes the findings, discusses their implications, and evaluates whether the hypothesis was supported or not. It may also highlight any limitations of the study and suggest directions for future research.
No, a hypothesis is not always supported by research findings. In scientific inquiry, a hypothesis is a testable prediction that can be confirmed or refuted based on experimental or observational data. Results may support the hypothesis, lead to its rejection, or indicate that the hypothesis needs to be revised or refined. The process of testing hypotheses is fundamental to advancing knowledge in science.
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!
The conclusion in the scientific method comes at the end of the process. After forming a hypothesis and conducting experiments to test it, researchers analyze the data and draw conclusions based on their findings. This final step helps to determine whether the hypothesis is supported or refuted, guiding further research and inquiry.
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.
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
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
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.
Bay City Rollers ended in 1983.
High Rollers ended on 1988-09-09.
The arch bridge is primarily supported by compression. In this design, the weight of the bridge and the loads it carries are transferred along the curved structure of the arch to the supports at either end. This allows the materials to handle compressive forces effectively, making arch bridges both strong and durable.
A cantilever is a structure supported at one end only, such as a diving board
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
A beam bridge consists of a horizontal beam that is supported at each end by vertical piers or abutments. The beam carries the load applied to it, distributing the weight to the supports. This type of bridge is simple in design and is commonly used for short spans due to its straightforward construction and cost-effectiveness. However, it may not be suitable for longer distances without additional support.
Bridge End railway station ended in 1948.
The Brooklyn Bridge is supported by a combination of its massive stone towers and a system of cables. The two main towers, made of granite, provide vertical support, while the suspension cables, anchored at each end of the bridge, distribute the weight of the roadway and traffic. These cables are further reinforced by smaller vertical suspender cables that connect them to the bridge deck, allowing for a stable and resilient structure. This innovative design was a significant engineering achievement at the time of its completion in 1883.
