Not only the Problem I have attached in Picture, but there are few more where I get different answer while solving by taking Moment Component and by Common Perpendicular.(adsbygoogle = window.adsbygoogle || []).push({});

[NB : The problem Stated in 'Engineering Mechanics' by Ferdinand L. Singer. Process 3 is what I did, Process 1 is what is done in the Book & Process 2 is done for Verification by me]

It is clear that the Book is correct, but I cannot find out why my answer [Process 3] is not Matching.

No book can Clarify the Issue except a Real Teacher. I am Confused & Waiting eagerly for the Answer.
