Question

I am confused about how to get the final answer, I know how to calcualte till up to the final answers, I have a feeling it might be simultaneous equation, however when I compute it, it come out as a wrong answer. Can someone help me with this specific part, outlining details on how to solve these types of simultaneous equations. Link is http://image.slidesharecdn.com/ch3statics-110110183217-phpapp02/95/slide-3-728.jpg?1294706410 Thanks Please show step by step solution to this problem, useing simultaneous equations.

Explanation / Answer

please do rate the answers .. :):)

there are the 2 equations we have

FBD *0.5 - FBC*0.7071 = 0

and 0.886FBD + 0.7071FBC = 29.43

steps :

we have to eliminate one variable here

as , we have FBC's constants common ,we choose to add the 2 equations

=>1.386 FBD = 29.43

=> FBD = 21.5 -------------ANSWER

now put this value back in any of the 2 equations to get F(bc)

hope it helped :) ..please rate me first
