Here will be horizontal reaction at e, hae and vertical and horizontal reaction at a, ba, hae.
00:09
Overall diagram taking horizontal reactions hae plus ha is equal to 0 and along vertical reactions ba is equal to 3000 plus 1000 which is 4000.
00:21
So taking moments about a, we have hae multiplied by 9 plus 3000 multiplied by 4 plus 1000 multiplied by 6, hae is equal to 2000, hae is equal to minus 2000.
00:37
The strut members aj, cj, cd makes 56 .3 degrees with the horizontal and the members if, fg makes 36 .86 with the horizontal.
00:49
At e along x, hae plus ed is equal to 0, hae is equal to ed.
00:55
So here along y no reactions at f along x minus fd cos 36 .86 degree minus fi cos 36 .86 degree plus fg cos 36 .86 degree is equal to 0.
01:13
So fd minus fi plus fg is equal to 0.
01:17
Along y we have fd sin 36 .86 minus fi sin 36 .86 minus fg sin 36 .86 minus fh is equal to 0.
01:32
From here we will have fh as 0 .599 times fd minus fi minus fg.
01:41
Now along x we will have ih minus ci minus fi times 0 .8 is equal to 0.
01:50
Now along y here we have pi minus ij plus fi times 0 .599 is equal to 0.
02:00
At h along x, fh is equal to 3000.
02:03
Along y, ih is equal to hg along x.
02:07
At g, gh plus fg cos 36 .86 is equal to 0.
02:13
Along y, 1000 is equal to fg sin 36 .86.
02:20
So here we have fg is 1667 .05 and gh is 1333 .81...
