Maximum compressive stress in developed at the top layer. And maximum tensile stress is developed at bottom fibre due to elongation of fibre.

L D Garg said: (Jul 7, 2013)  
Loaded means loaded downwards. In that case upper fibers will be compressed while lower will be expanded. Hence maximum compressive stress will be developed in top layer.

Chandrakishor Pal said: (Oct 7, 2013)  
Top layer concave shape gain and bottom layer convex shape so top layer is compressive stress.

Md Hamza Kamal said: (Oct 10, 2013)  
When the loaded in rectangular beam, then will be developed maximum stresses in bottom and top layer.

Pushpal said: (Oct 27, 2013)  
The answer which is given that is only true for when load is applied transversely downward.

Omkar said: (Nov 28, 2013)  
Can anyone explain the meaning loaded transversely?

Vipin said: (Dec 5, 2013)  
What is the diff b/w Transverse load and direct load?

Manish Thakur said: (Dec 15, 2013)  
If beam is cantilever then max. compressive stress will be in the bottom fibre but in case SSB max. compressive stress will be in the top fibre.

Sangeeta said: (Dec 19, 2013)  
Due to transverse load the beam is sagging, so that's the compression is developed on top layer.

Nishanth Kallada said: (Dec 29, 2013)  
Max compression will be on top layer and this will decreases towards neutral layer and becomes zero at neutral layer, after that stress will be tensile and value increases and reaches max at bottom layer.

Katrina said: (Jan 17, 2014)  
Maximum tensile stress is developed at bottom fibre due to elongation of fibre.

Naveen said: (Jun 28, 2014)  
What is transverse loading?

Dheerendra said: (Aug 2, 2014)  
Any load perpendicular to the longitudinal axis of beam.

Subhendu said: (Nov 27, 2014)  
The answer is totally correct. You all forgot the meaning of stress, it is the resisting force, when the beam is loaded transversely, tensile force will act on the bottom layer. So to compensate the effect, compressive stress will act at the bottom layer.

Kiran &Amp; Anuraj ,Professors said: (Dec 9, 2014)  
The answer is top layer as the compressive stress are developed maximum at the top layer. No doubt regarding the answer.

Devanesan Andrews said: (Jun 24, 2015)  
Its actually according to the type of the beam. So data in the question totally insufficient.

Raj said: (Jul 22, 2015)  
@Devanesan Andrews.

Question is sufficient. It is transversely loaded.

Anant Kant Krishnan said: (Sep 6, 2015)  
The loading condition in case of a leaf spring can said to be a transverse loading, and in this case the top layer will be under tension and bottom layer will be under compression.

Chetan said: (Oct 15, 2015)  
Load is applied transversely downward means top layer will undergo compressive stress and bottom layer under go tensile stress.

Rajeev said: (Dec 2, 2015)  
Since type of beam is not defined so it difficult to give the answer.

Siva said: (Dec 2, 2015)  
For beam the load applied always downward, so the answer is top player.

Mohsin said: (Jan 7, 2016)  
Some books mention top layer and some books mention bottom layer. I am confusing.

Smit said: (Feb 9, 2016)  
If the beam is loaded in zagging then top layer is in compression and bottom layer is in tension and if it is in hogging then vica versa.

Ajitesh said: (Aug 10, 2016)  
The correct answer should be (A).

Vicky said: (Aug 16, 2016)  
The answer is A.

It's just like turning the pages in a book, where the bottom layer compresses and the top layer expands.

Hasiba said: (Sep 26, 2016)  
I think, option A is the answer.

Krishna said: (Sep 28, 2016)  
The correct answer is option A.

Vikash Kumar said: (Oct 6, 2016)  
Not cleared with this question, Please explain me detailed.

Pavankumar said: (Oct 16, 2016)  
I think the answer for the maximum compressive stress is developed on the top layer of the beam.

Umesh said: (Nov 7, 2016)  
That is apply for only cantelever beam.

Koribilli Hemanth said: (Nov 10, 2016)  
There is no clarity in question, here it should mention which type of beam is loaded.

For cantilever beam "bottom layer".

For ss beam "top layer".

Smvec said: (Nov 17, 2016)  
May be:.

"When a rectangular beam is loaded transversely".

Load = rectangular beam.

Rectangular beam is made to load transversely (vertically) on a surface (longitudinal axis).

Then "the maximum compressive stress is developed on the [A]. Bottom layer".

Chandan Kumar said: (Nov 21, 2016)  
As, I think top fibre is the most suitable answer.

Himanshu said: (Dec 2, 2016)  
According to me, question is insufficient because the loading condition is not given that is it a simply supported of cantilever.

Ravi said: (Jan 5, 2017)  
Top fibre is right answer.

Tarun said: (Feb 2, 2017)  
The loading profile is not stated. So I can not understand how can one answer this?

If the beam is cantilever beam then it will bend concave down and the bottom layer is in compression.

For a simply supported beam, the bending profile is concave up so top layer will be compressed.

Neeraj said: (Feb 12, 2017)  
Agree @Tarun.

Pranay Sb said: (Feb 23, 2017)  
Here it is mentioned the type of loading. The given answer is correct only for Cantilever Beam.

You are correct @Tarun.

Aneesh Kushwaha said: (Mar 23, 2017)  
Yes, Agree @TARUN.

Chandra Prakash said: (Apr 15, 2017)  
I think Option A is the right answer.

Pramod Kumar said: (Apr 22, 2017)  
I think Option A is the right answer.

Ravikumar said: (May 28, 2017)  
Transverse load means load which is perpendicular to the neutral axis.

M. Vidisha said: (Jun 1, 2017)  
Here loaded transversely mean load acting downwards i.e. perpendicular to longitudinal axis of the beam, definitely question is the insufficient type of beam should be mentioned.

If it is cantilever beam answer would be bottom later.

If it is SS Beam then the top layer.

Kuldeep said: (Jul 11, 2017)  
Stress will depend on type of beam.

Paresh Purohit said: (Jul 23, 2017)  
If it is cantilever beam answer would be a bottom later.
If it is SS Beam then the top layer.

Dr Ravi said: (Aug 9, 2017)  
Answer is correct if it is a cantilever. It is wrong if the beam is simply supported.

Pradeep Gk said: (Oct 8, 2017)  
If it is cantilever beam the answer would be bottom later.

If it is SSB then the top layer.

Transfer load means acting perpendicular to the beam axis.

Jatinder Kumar Prajapati said: (Oct 12, 2017)  
A should be the correct answer.

Navaj Mulla said: (Dec 12, 2017)  
Given answer is correct because actually stress means internal pressure to resist external loading as it is loaded transversely compression is at top and tension is at bottom but to resist bottom tension there should be compression force is required and this internal compressive force per unit area is nothing but compressive stress at bottom. So answer b is correct.

Anusha said: (Jan 19, 2018)  
I agree @Navaj.

Ramesh said: (Apr 11, 2018)  

If so, why there is compressive stress at the bottom in case of cantilever beam?
