If: A=Horizontal distance betwen ends (at same height) B=Depth of catenary C=radius of curvature at lowest point L=length along catenary M=Mass per unit length Tm=Tension at ends of catenary To=Tension at lowest point. (Also horizontal component of tension at any point) Then: C=To/M, and B=C(cosh(A/2C)-1)

Sag produced in the conductor of a transmission line depends on?
-The tension of the cable (the tighter, the less sag, but this can cause other problems if too tight) -The temperature outside (the higher the temperature, the more it will sag) -The amount of current flowing through the cable (the more current, the hotter the conductor will get = more sag) -The type of cable (aluminimum will sag more than copper; ACSR will sag less than straight aluminimum).
When Ontario Hydro workers set up electrical cables during the summer they allow the cables to sag. Suggest a reason for this. In your answer refer to the particle theory?
i know someones going to be on this sooooooooo....... they sag because the hydro workers know, from the heat the cbles will sag during the summer, so they start the sag so they cant sag anymore
How do sag's in power transmission formed?
The plural of sag is sags, not sag's! Sag is caused by the weight of the conductor between its supports, and is (a) unavoidable and (b) necessary to allow for the conductor's expansion and contraction during variations in temperature. When surveyors design a power line, the amount of necessary sag is calculated and built into the design, while ensuring that the clearance between the conductor and the ground remains within safe limits.
What is the strongest arch?
Tacoma narrow bridge.
What is Sag Compensating Springs for Pantograph Isolator?
i think sag compensation springs are used in dead end termination of quadra conductor bus where jack bus is passing below bus & required clearence if we are not getting betn two buses their these sag compensation springs are used to bring conductor under tension .
What is sag in transmission lines?
Catenary
How do you calculate the sag between two transmission poles?
To calculate the sag between two transmission poles, you can use the catenary equation which considers the weight of the span wire and the tension in the wire. The formula takes into account the span length, weight per unit length of the wire, and the tension in the wire to determine the sag. It is important to ensure that the sag is within acceptable limits for safety and operational purposes.
What is the formula in calculating catenary?
The general formula of a catenary is y = a*cosh(x/a) = a/2*(ex/a + e-x/a) cosh is the hyperbolic cosine function
What is catenary in steam turbine?
generally more than three shafts contact by coupling together in steam turbine. the shaft is heavry and will be sag. in order to reduce the bend force on coupling and bend force on bearing, the engienering calclated the shaft and simulated when its in operation condition. so, the catenary curve and bearing elevation data have been provided for steam turbine installation.
How do you prove lens formula?
sag hight of lense 1.53 ? radius of lense index 1.498
What is catenary taping?
Catenary taping is a technique commonly used by athletes to provide support and stability to muscles and joints. It involves applying specialized elastic tape in specific patterns along muscles and tendons to help reduce pain, improve performance, and prevent injuries. The tape is designed to mimic the elasticity and thickness of human skin, allowing for a wide range of motion while providing support.
Expressions used in catenary taping?

What is to hang or sink downward?

Why catenary important in alignment of turbine?
A catenary is the shape formed by a hanging chain or cable under its own weight. In wind turbine alignment, the catenary is important because it helps to position the turbine blades in a way that maximizes their efficiency in capturing wind energy. By aligning the turbine blades along the catenary curve, the blades can better adapt to changing wind conditions and generate more power.
What is the strongest shape underground Catenary or Hemisphere?
sphere
What is a equation for a catenary with a 2?
A equation is santa clause
What are the similarities between parabola and catenary?
The Catenary and Parabola are different curves that look similar; they are both "U" shaped and symmetrical, increasing infinitely on both sides to a minimum.
