Hi, here in this given problem suppose this dot is representing the spider -man.
00:07
This is one of the web string.
00:10
This is another web string, first web string attached with the first half of the ferry.
00:17
This second web string attached with the second half.
00:20
T -1, tension in the first one t1, tension in the second one that is t2.
00:25
Angle.
00:26
The first one is making an angle with a horizontal theta 1 the second one is making an angle theta 2 so this theta 2 and t 2 these both are missing provided mass of the spider -man m so his weight will be m g acting vertically down the given is theta 1 which is 9 .00 degree tension t1 which is 4 ,450 newton mass of the spider -man that is 76 .0 kilogram.
01:09
Now we take components of these tensions as we know if this angle is theta -1, this angle here that will also be theta -1.
01:20
So the component, horizontal component, t1, cost -theta -1, vertical component, t2, sorry, t1, sine theta -1.
01:38
For this t2, horizontal component, t2, cost theta 2, because this angle will also be theta 2.
01:46
And vertical component t2 sine theta 2.
01:51
So as the spider -man is in equilibrium, so in this condition of equilibrium, t2, cost theta 2, that will be equal to t1, cos -theta 1 and we can consider this to be the equation number 1...
