Let's discuss this question.
00:02
So here we need to determine the reaction sag and tension of the transmission line at 65 degrees celsius in still air.
00:10
So here we can say area is given as 240 millimeters square that is equal to a and overall diameter is equal to 20 millimeter that is equal to d and weight is equal to 1 kilograms per meter.
00:36
Ultimate strength is equal to 800 kilograms and here coefficient of linear expansion is equal to 18 .44 multiplied by 10 to minus 5 degrees celsius and here radial is thickness is equal to 1 cm so here we can say t1 is equal to 8 ,000 divided by 2 which is equal to 4 ,000 kilograms.
01:29
So t will be equal to 65 minus of minus 5 that is equal to 70 degrees celsius and alpha is equal to 18 .4 multiplied by 10 raised to minus 5 degrees celsius.
01:46
And here e is equal to 93 to 0 kilograms per meter square and length is equal to 150 meters.
01:58
Here we can say weight of conductor, weight of ice per meter is equal to 910 multiplied by 5t divided by multiplied by d plus t.
02:19
So here we can say this is equal to 910 multiplied by 3 .14 multiplied by 10 multiplied by 20 plus 10 multiplied by 10 raised to minus 6.
02:30
So this will be w1 that is equal to 0 .8...
