Civil Sum Up

  Solution: For QA001 This is a simple problem but tricky. let's do it  Step 1.  Take a section x-x on the PQ member, and draw the free body diagram Here, Suppose the force in PQ member is V KN, and Take the length of the cantilever is L  Step 2.  Find out the deflection in Point Q As per the principle of superposition,                           Upward deflection = Downward Deflection                 Step 3.  Put the given data  Step 4. hence the force in the member PQ is = 50 KN. Answer A is correct.

Q. Find out the minimum time (in Days) for the completion of the project. Sol:  This is a simple problem,  here, the longest duration path will give you that minimum time for completion of the project, and that path is also called a critical path.  So, critical path duration is the minimum time for project completion. Step 1: find out the possible paths  So, the following paths are possible                                                        A-B-C-E-F-J-K-L                     = Tota Duration = 1+7+30+25+7+7+3+1= 81 Days                                A-B-C-Dummy-G-H-I-K-L   = Tota Duration = 1+7+30+25+7+7+3+1= 81 Days ...

# 5 best websites for civil engineering students for practice MCQ and materials. If you have a clear concept that is your advantage, I will suggest you, keep practising until you succeed in life. Here are some of the websites I personally follow to practice and brush up civil engineering concepts online, and yes that is totally free of cost. you can check it to do the same. # 1. Indiabix.com It is one of the best sites for practising all types of questions.
