the current causes alternating magnetic fields which shake the wires and they get warm so snow and rain sizzle off the wires.
They are to make the high tension wires visible from a distance.
noyou can not
33 kV line, it should be 3.7 mtrs
To my knowledge, Melde's Experiment is to do with standing waves in wires under tension. Accordingly, perhaps you should explain exactly what you are referring to?
some simple machines do need wires and some dont
High Tension Wires was created in 1989.
I drove under high tension wires in a truck and could clearly hear a buzzing noise. I actually stopped the truck and sat under the wire for a moment to listen to the sound. As I recall it was a very humid day. I don't know if this is true but suspect the damp air had something to do with it.
The high tension does not mean mechanical tension, it means high voltage, generally in the hundreds of KV

High tension electrical wires
yes but 3 yrs
That is the normal colour of aluminium.
engine pulls the aircraft forward but air resistance tries to hold it back results in tension which tries to stretch..............2)bracing wires are subjected to tension
A word relating to electricity is high tension wires.
They are to make the high tension wires visible from a distance.
1.The wind blows hard to create a sound so when the wind blows the wires start shaking and making another sound so together they make a loud sound. 2. When the wind blows through the telephone wires the wind blows the wires forcing them to vibrate. so technically because the wind makes the telephone wires vibrate. your welcome.
The system that you describe is said to be statically indeterminate since, there are more than 2 wires (minimum required to support the cement bag with inclined support).There are three unknowns in the system that is the tensile forces in the wires. You should use three equations as follows to solve this.Vertical equilibrium: Sum of vertical components of tension in all wires is equal to the weight of 380NHorizontal equilibrium: Sum of horizontal components of tension in all wires add to zerCompatibility condition: The vertical component of elongation of all wires is the same.Formulate the three equations and solve the algebraic equation to get the tension in each wire.
