Of md is equals to 0.
00:04
So, ay into 9 plus 6 into 3 that is equals to 9 into 6 plus 12 into 3.
00:16
So, here the value of ay comes to be 8 kilo newton and the value of ax is equals to 6 kilo newton.
00:25
So, summation of fy is equals to 0 say ay plus by is equals to 9 plus 12.
00:38
So, the value of by is equals to 13 kilo newton.
00:43
Consider joint a, here is the joint a, if we look this the force is ab here acting in this direction and here is a force at angle 40 degree and the force is faf and here another force, this is in this direction, here another 6 newton is acting and here 8 newton is acting.
01:10
So, consider summation of fy is equals to 0.
01:16
So, faf is equals faf into sin 40 degree is equals to 8.
01:25
So, faf is equals to 11 .313 kilo newton, then summation of fx is equals to 0.
01:36
So, fab is equals to faf into cos 45 degree cos sorry cos 45 degree sorry it is cos 45 and here also it is 45, this is 45 degree and this is 45 degree...
