Two snow cats in antarctica are towing a housing unit to a new location as shown in the figure.
00:09
The sum of the forces f .a and fb exerted on the unit by the horizontal cables parallel to the line l.
00:17
And fa is 4 ,500 newtons.
00:21
So we need to find a value of f of b.
00:28
Alright, okay.
00:30
Two snow cats in antarctica are towing a housing unit to a new locations.
00:36
Okay.
00:38
And the sum of the forces exerted by is parallel to the line.
00:42
Okay.
00:43
So this is what is given over here.
00:44
The sum of the two forces on the unit are are parallel to the line.
00:49
It means that their horizontal component is actually getting cancelled out.
00:53
If we make components, it will be f -a -sign of 48.
00:57
This will be f -b -sign of 32.
01:01
And on the top, it's going to be f -a -cosine of 48 plus fb cosine of 32 now since they are saying that their sum is exactly parallel to the lines definitely these two should be equal right they should cancel out so that there's no component which is over in the horizontal direction this means that if b sign of 32 should be equal to f a sign of 48 degrees if that is the case then what is f b f b is going to be f a sign of 48 over sign of 32...
