steel wire cables

This type of wave propagation is said to be unguided. The uniform plane wave exists throughout all space. The electromagnetic energy associated with the wave spreads over a wide are..

Resists corrosion Utensils, ornamental pieces Manganese steel 10 - 18% manganese Very hard and resistant to wear and tear Grinding machinery, safes Nickel steel 2 - 4% nickel Resists corrosion, hard and elastic Wire cables, gears d..

Steel — Alloy Property/ Reason for alloying uses Stainless steel (Fe, C, Ni, Cr) Lustrous, resistant to corrosion, high tensile strength Alloy: Acquires brilliant silvery shine on alloying with Ni, Cr Utensils, cutlery, automobile parts Nickel ..

This is also an alloy of steel with 3.5% nickel. It is used extensively in cable preparation. This is flexible than stainless steel..

A steel wire is tied from a point on the ground to the top of an electric pole whose height is 20 ft. The wire makes an angle of 70° with the horizontal through the foot of the pole. Find the length of the wire. => 58 ft or 8 ft or 21 ft or 55 ft..

A steel wire in the form of a circular ring of radius 4 m is straightened and cut into 3 equal pieces. Find the length of each piece. => 18.37 m or 8.37 m or 4 m or 25.13 m..

The smallest conductor used in standard open-wire telephone circuits is No. 12B and S. gauge. A line of such construction will have a loss of approximately 0.06 db per mile. Cable circuits, on the other hand, make use of conductors not larger than No. 19, and a typical cabl..

A telephone cable at a place has four long straight horizontal wires carrying a current of 1 ampere in the same direction east to west. The Earth's magnetic field at the place is 0.39 gauss, and the angle of dip is 35 o . The magnetic declination is nearly zero. What are the re..

An optical fiber is a dielectric wave guide that transports light signals from one place to another just as a twisted-wire pair or a coaxial cable transports electrical signal..
