Hello students, let's solve this question here.
00:03
By writing the equation of equilibrium, that is, summation fx is equal to 0, it is ac into cos of 30 degree plus 290 is equal to 0.
00:19
Therefore, ac will be equal to 334 .8 lb.
00:26
Now, summation fy is equal to 0, that is, minus ac into sin 30 degree plus cd is equal to 0.
00:39
Therefore, cd will be 167 .43 lb.
00:46
Now, by using the cut section of dcd, we can say that, summation fy is equal to 0, where nd minus 334 .8 into sin 30 degree is equal to 0.
01:06
Therefore, nd will be equal to 167 .431 lb.
01:13
Now, let's consider the triangle, that is, acf, where it is having an angle of 30 degree...
