A suspension bridge is supported from a height of 30 feet. The length of the wire used to suspend the bridge, from the ground to the top, is 65 feet. What is the angle of elevation from the base of the bridge to the point of suspension?
What is the bridge made of?
The Verrazano-Narrows bridge connects Brooklyn and Staten Island and is named for Giovanni da Verrazzano. The bridge is constructed from concrete pilings, steel wire cables, iron eyebars, steel girders, and steel towers.
What is the cause of resistance and how the resistance of wire can be determind?
The cause of resistance is the opposition to the flow of charges.Resistance occurs due to the collisions between charges inside a substance. The resistivity of a wire can be found out by using a meter bridge or a slide wire bridge.
What is the severn bridge made out of?
The Severn Bridge is located close to the former Aust Ferry. The bridge is a suspension bridge of conventional design, with the deck supported by two main cables slung between two steel towers. In 1966 the cables supporting the bridge deck were spun from 18,000 miles (29,000 km) of wire[5]. The bridge is 5,240 ft (1,600 m) long, consisting of a 3,240 ft (988 m) central span between the towers and the two 1,000 ft (305 m) side spans. The towers rise to 445 ft (136 m) above mean high water and are of hollow box construction. The deck is an orthotropic steel box girder of aerofoil shape with cantilevered cycle tracks and footway supported from the box
Contains both resistance and inductance?
Wire. conductors. Wire made into a coil, an inductor.
Viva questions on Carey foster bridge?
we can measure the resistance of the given wire using the carey foster bridge / ?
What is the function of a Carey foster bridge?
A Carey-foster's bridge is a modified version of the meter bridge (wheatstone bridge or potentiometer). It can be used to find out the average resistance per unit length of the meter bridge wire and hence find out the unknown resistance. It is more accurate and more sensitive than a meter bridge.
What is the principle of Carey foster's bridge?
the principle of wheatstone bridge is,there is a potential fall is directly proportional to the length of the wire, and this fall is also equalt to the fall accross the resistances applied in parallel to the battery. It is a form of wheatstone bridge.
What is the way the Brooklyn bridge made?
The Brooklyn Bridge is a suspension bridge made from wire cable.
What covers the Brooklyn Bridge?
The Brooklyn Bridge is made of wire cable.
Can you use wire to support a bridge?
Yes. They're called suspension bridges. The Golden Gate Bridge outside San Francisco is one of them. The suspension cables are made out of wire. Very thick wire but wire non the less.
What is the Rio-Antirio bridge made out of?
metal concrete wire plastic steel
What is golden gate bridge made out of?
the golden gate bride is made out of 27 572 strands of wire on each cable
What two technical advancements made the building of the Brooklyn bridge possible?
The Brooklyn Bridge was the first suspension bridge to use steel for its cable wire and the first to use pneumatic caissons.
What bridge is supported by wire and attached to towers?
A suspension bridge.
Are there any videos where metre bridge, commutator and Peltier's effect are explained together?
(a) The connection between the resistors in a meter bridge is made of thick copper strips because the resistivity of a copper wire is very low. As, the connections are thick, so the area becomes large and the resistance of the wires becomes almost negligible. (b) It is preferred to obtain the balance point in the middle of the meter bridge wire because it improves the sensitivity of the meter bridge. (c) Constant is used for meter bridge wire because its temperature coefficient of resistance is almost negligible due to which the resistance of the wire does not get affected on increasing temperature of the wire during flow of current.
