[@shivaprasads6606]

for engineering students these lessons are very useful and thanks for all your videos

[@temet01]

First of all thank you for giving us more clarification on deflection of beams . But I have a question ,when x=o, how C2=0??, please check it at x=0, C2 is not equal to zero.

[@neharadhp9944]

youre right!

[@swapnilk.b1396]

so.. I was not wrong.

[@swapnilkumar7432]

Since the beam is symmetric therefore the slope at either side of the beam extremities should be equal. I guess the problem here is that, for taking the slope at left hand side reaction just the first part of slope equation should be considered..

[@Joe_SZN]

Thought that too 😅

[@manupriya280]

At both ends the slope magnitude should be same because of symmetry but you are getting different value sir.

[@rajeshseetha9686]

I too have the same doubt

[@metro......3977]

you are right. but sir didn't neglect the Macaulay's function when found the maximum slope in point A(x=0). that's why values are change

[@deepaksah8667]

sir,Slope at A and B should be equal in magnitude(by symmmetry)?? plz rply.

[@dheerajkataria9603]

Sir where u come from.. I have never seen a single teacher as like you in my whole life from schooling to engineering.. It is clearly visible that how you teach the students in very much intrested way and your skills is awesome that make u different from others.. Thank u very much to teach complex and confusing topic of engineering in a easy and interested way.. Many times i am trying to understand this but never understand becz of feeling boring and a lot of confusions.. But today i have totally understand macaulay method and feeling proud and happy..

[@JK-ql2yp]

U haven't understand anything

Slope at end are always Equal but change in sign then how slope at A become = -3WL²/16EI ??? In general Slope at ends are always WL²/16EI in simple supported beam at load in the center

When you put X=0, Y=0 at that time you neglect the second step of the equation but when you put X=L, Y=0 at that time you did not neglect why sir?

[@saurabhmaurya6031]

because second step for second section only and first section is valid for 1st section only

Thank you so much professor.

SLOPE AT A AND B SHOULD BE WL^2/16EI. NOT SLOPE AT A IS 3WL^2/16EI AND SLOPE AT B IS WL^2/16EI.

if length becomes 2L and one end is load is W on length L and other load is on 2L so how to solve this problem sir.

Sir in which case section is take in right hand side direction

Why do we consider only first section in first boundary

Grateful to you for bringing an error to our notice and helping us by giving us an opportunity to alter it to a correct one soon.

[@popularfunny1583]

Why we remove that section in first boundary condition, why not in second

[@swaroopsai9657]

Hello sir...While ur teaching 3 page it must be w/2 but why u wrote only w..

[@arjunshirsath8353]

more problem should be taken on different type of beam..................

[@venkatesh2285]

In this problem the given beam is symmetric. when the bean is symmetric means slope at A will be equal to slope at B. BUT here in this problem the answer for slope at A is not equal to slope at B. HOW IT IS CORRECT?? COULD YOU PLEASE CLEAR MY DOUBT?

[@Sunny55333]

Venkatesh janakiraman slope at a and b are same as the load is symmetric...he has done a mistake in calculations...!!

[@abhishektambe1000]

Yes you're right the slope should be same for both A and B but at A slope will be positive and and at B slope is negative

[@venkatesh2285]

I have found that where he has commited the mistake. in order to calculating the slope at A SHOULD not consider the full equation only should have to consider upto C1 in the slope equation then only slope will be equal to A AND B. please kindly verify this one. Thank you

But if we consider upto C1,we will be getting same values of slope but the sign is opposite.. please clear my doubt..

@@perfectmaster9 yes the signs will not be the same meaning that we should not consider the first section till C1

Then get lost u bloodyfool person.. It is for our better understanding to help students their concepts strong step by step.. If we missed any petty value.. So that will become a big problem for us to finding the mistake in whole solution.. Becz this method wants practice and concentration to every steps clearly...

[@magnetar_nks5514]

The method that has bee used to find the deflection of slopes, is wrong as the brackets behave as unit step function according to macaulay,but you have just neglected the brackets while calculating slope and deflection, whereas while applying boundary condtn used it

[@asimkumar174]

sir while finding c1 you have neglected the second part of deflection equation while in finding c2 you concluded it.. please explain this

[@mandasings7043]

yes sir.... c2 is not zero....

[@sachinkumar064]

Why are you not considering the support reaction at B, while taking moment about the section X-X ??
