Hello, in this question we are given at us.
00:03
So it's something like this and yeah, this is a, this is b, c, d, e, f, g and h.
00:34
And we need to calculate the force in c g, this member.
00:39
So force acting are here it is 4 kiloton, this is 5 kiloton, and this is given to us that is 7 kilometers i guess so and dimensions are 4 meter 4 meter 3 meter 2 meter this is 4 meter this is 4 meter this height is 3 meter and this height is 2 meter all right so first of all we will calculate reaction at this e and at this a so the reaction could be directly calculated reaction at e would be what 4 into 4 plus 7 into 8 plus 5 into 12 divided by 16 so this would be reaction at e let me write it 4 plus 7 into 8 plus 5 into 12 divided by 16 so it is 8 .25 kiloton and reaction at a would be 4 plus 7 plus 5 minus and so that would be 7 .75 kilocton.
02:08
So the xenet a and reaction at c is 8 .25 and 7 .75 kilocton.
02:17
Now what we will do? we will calculate these angles.
02:20
This angle theta.
02:22
This angle theta...
