Can you explain why the internal moment is clockwise of 10 ? Should i explain in this way ? Since internal moment = reaction moment , so at left of A , the moment resultant = 10Nm anticlockwise , reaction moment has to be 10NM clockwise ??

The moment is clockwise , so they it's neagtive -10 as stated by the author , right ? anything wrong with it ?

Do you mean that to produce sum of moment = 0 , the moment should counter The moment at AE= 5(2) - 10(2) = -10(anticlcockwise) , so , the moment is clockwise ?

Homework Statement I don't understand why the fixed end moment at AE is 10KNm ( clockwise) . Homework EquationsThe Attempt at a Solution Forger about the sign convention here , i have the resultant moment = 10KNm , which ic clockwise , why in the 2nd picture ( SFD and BMD part) , the moment...

Homework Statement I have problem of obtaining the cross sectional area . Homework EquationsThe Attempt at a Solution Taking section 2-3 as an example , my working is [ (3.3 +4.8) / 2 ]* 5 = 20.25 , but the ans provided is 29.28 , how to get the 29.28 ?

why ? here it is

Homework Statement In my book , i was told that when the drainage of surface is high then the surface runoff will be low . However , i don't think it's correct . Homework EquationsThe Attempt at a Solution Definiton : Runoff can be described as the part of the water cycle that flows over...

Are you familiar with plastic analysis ? Zp here is the plastic modulus . I use another method to do , but i get different answer , why ? Here's my working : , Zp = Sum of area x ( difference between centroid of particluar area and the equal area axis ) Zp = [ (130)(20)(150-10) +...

Homework Statement For this shape , it's clear that the centroid and the horizontal line of equal axis lies on the same horizontal line , am i right ? Homework EquationsThe Attempt at a Solution I'm not sure . correct me if i am wrong . [/B]

So , the flow is only vertical flow ? no horizontal flow ?

Previously , you pointed out that the flow is horizontal , if so , why there's no horizontal permeability in this question ?

sorry , wrong thread

@Chestermiller , can you help ? I think you are the only one in this forum who knows soil mechanics

Update : Why the max shear will only occur at B when the certain load act on it ? Can someone explain about it ?
