How long is the kintai bridge in miles?
Kintai bridge is 175 meters long. It is located in Japan.
Whyis the bridge supported at one end by rollers?
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.
Which bridge is the simplest and oldest desighn?
I would say the arch bridge because the Romans used it, but I'm not completely sure. Beam and pillar as used by the Egyptians.
Why soldiers are told to not march while crossing abridge?
Harmonics. Most bridges are strong enough to support the weight of soldiers marching in lock step, but the constructive vibrations still hasten the need for repairs. Harmonic vibrations induced by the wind brought down the Tacoma Narrows Bridge, "Galloping Gertie."
Worlds biggest arch dam?
The longest bridge in the world is the Danyang-Kunshan Grand Bridge. It is located in China, and is a railway between Shanghai and Nanjing. The bridge is 164,800 m long and 80 m wide, and was completed in 2010.
How does thermal expansion affect a bridge?
A bridge must have expansion gaps or else they will waver when they expand in warm temperatures. This is thermal expansion
How would changes in temperature would affect a bridge?
Thermal expansion means that the length of the bridge changes.
Why is it important to take thermal expansion into account when buliding bridges?
because in the summer, its hot and the bridge will expand and if you dont have enough room to expand the bridge will crack under pressure and in the winter the bridge may shrink a bit and might also crack. hope it helps :)
Use thermal expansion in a sentence?
When the metal bridge heated up in the summer sun, it expanded due to thermal expansion, causing the joints to shift slightly.
What happens when one of the diodes is removed from the bridge rectifier?
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.

What are the type of pre commissioning testings done before commissioning a electrical substation of voltage rating 110 kilovolt?
Depending on the equipment required for the substation,some of the tests are as follows: meggering,hi-pot testing,continuity checks,c.t. testing,relay testing,ngr testing, capacitance bridge test's on transformers.
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.
When molecules move closer together in a bridge during winter how does a bridge not break from the molecules coming closer together?
They design bridges with mechanical sliding gaps to avoid any damage due to thermal expansion/contraction.
What is a bridge megger?
A bridge megger can be used for resistance measurement and fault locationIt is so known because it measures high (mega-ohm) resistances, and uses a bridge circuit, which is suited to this type of measurement.Visit Test Equipment Connection for new and refurbished Megger Testing Equipment
If the weather is very hot the pavement of a bridge can heat up enough so what takes place?
If the weather is very hot, the pavement of a bridge can heat up enough to cause thermal expansion, leading to the materials expanding. This expansion can create gaps or misalignments in the structure, potentially compromising its integrity. In extreme cases, it may even result in buckling or warping of the pavement. Engineers often account for this thermal effect in bridge design to ensure safety and longevity.
