Dear Applicant,

I hope you are doing well.

Dont feel anxious about your exams. They will appear sooner or later. What I can say is be prepared for them study well. Keep yourself calm getting anxious about it wont help you out much, infact you will be more stressed out and wont be able to absorbs any of your study material. So try to be calm as much as possible.

Most of the board exams for 12 start in the month of March. Before that in January you have prelims papers so put your best efforts in that paper and do your best. It will help you to boost your confidence and give you a sense of achievement. Usually prelim are abit tougher than your boards so give you best. It will all go easy. Exam are such creatures wherein if you are well prepared you can defeat it without much trouble.

Hope this helps. Do your best I wish you good luck !!

Dear Candidate,

You can search the same on various portals on internet for step by step method & better understanding. Kindly know, we are limited by our answering options, still I will try to help you.

1. Force on spring when pressure in reservoir is 1N/mm2

P1 = 491N

2. Force on spring when pressure in reservoir is 1.2N/mm2

P2 = 589N

Spring index, C=6, Wahl's factor

K = 1.2525

From tau find the nearest standard diameter, (Coil dia = 6*d = 29.262)

For number of turn, formula for deflection will be used

Delta = [(8*P*D^3)/(G*d^4)]*n , n= effective number of turns

Now,

P2-P1 = 98N

n = 9.2 (after calculating delta)

Actual number of turns with bent = 9.2+2 = 11.2

Now,

Initial deflection at P1 = (491/98)*4 = 20.04mm

Maximum deflection at P2 = (589/98)*4 = 24.04mm

Difference is of 4mm

Now,

Free length of spring

= n'*d + Delta(max) + (n'-1)*1.0

n'= actual number of turns

Therefore free Length of spring,

= 88.86mm(after calculating the whole equation)

Thanks. Hope it helped you a bit.

Khushi, you haven't mentioned your Category. Nevertheless, we have DU 8th merit list for 2019. . And going by that with 81%, you might have a chance in Aditi Mhavidyala, Aryabatta College, Bhagini Nivedita College and  Dr. Bhimrao Ambedkar Degree College. Now this is 2019 data and cut offs change every year. So while with 81% you might not get a seat in the first 6 Merit lists but yes either in the 7th or 8th merit list, you might get a seat in B.Com (//B.Com) . You can also check the 7th merit list at: http://du.ac.in/adm2019/pdf/Cutoff/Seventh/05082019_Arts%20&%20Commerce.pdf

Hello student ,

The HRD ministry is all set to launch Mano Darpan to help students cope with the stress of lockdown. MHRD will launch a set of guidelines prepared by the experts in Child Psychology. To ensure that each student stays away from stress and anxiety follow these steps -

Be up to date - This is very crucial for everyone. Be aware of the latest guidelines. Read articles issued by the government. But at any cost, avoid watching TV news channels. They are for your parents, not for you. Most of the TV news channels, keep a count of deaths. Knowing the number of deaths will do you no good. Prefer in shorts or simply your college bulletin.

Pursue a hobby - All of us have some talent that has been kept locked away. This is the right time to work on it. Painting, writing, singing, dancing, the list is endless. No one is going to rate you for how you are doing in these fields. They are just there to make you happy.

Talk to your friends .

Eat and sleep well .

Keep just 3,4 hours for your studies -Now there is nothing I can say for students going against JEE Mains or NEET. But the rest, take a break, guys. You got time to prepare for your exams. Go slow, yet steady.

Hope it will help you !
