In this question, solution here is take horizontal as x -axis and vertical as y -axis.
00:09
Apply the equilibrium equation.
00:11
Summation f of x is equal to 0.
00:14
A of x is equal to 0.
00:16
This is equation number 1.
00:19
And here, summation f of y is equal to 0.
00:26
A of y plus b of y is equal to 100 multiplied by 1 .5 plus 200 multiplied by 1 .5.
00:37
So this is equal to 150 plus 300 which is equal to 450.
00:45
This is equation number 2.
00:47
Now summation m of a is equal to 0.
00:50
So b of y multiplied by 3 is equal to 100 multiplied by 1 .5 multiplied by 0 .75 plus 200 multiplied by 1 .5 multiplied by 2 .25.
01:09
On solving, we will get here this equals to 112 .5 plus 675.
01:16
So this is equal to 262 .5 newton.
01:22
This is equation number 2...
