An aircraft of 10,000 kg mass is designed with the line of thrust 0.9 meters above the line of drag. In normal flight, the drag is 18.2 kN and the centre of pressure on the main plane is 150 mm behind the C. G. If the centre of pressure of the tail plane is 10 meters behind the C. G. , what is the load on the tail plane in trim condition?

sin y (dy/dx) = cos y (1 - x cos y)

Solve : (D^2 - 2D + 1)y = x sin x

Here's the problem.

Find the inverse Laplace Transformation of : s/(s^4 + 4a^4)

Hi,taking into account of recent hikes in tariff, please advise which mobile connection should I prefer-Airtel or BSNL?I do sms and gprs regularly and I am frequently on national roaming.So the preferences must include high internet speeds,good roaming network,voice clarity etc.Please do suggest.

Hi,I have accidentally deleted the message centre number.Please tell the message centre number of reliance mobile of kolkata circle.Please note that I do not need any free message centre numbers or similar types of hacks.

Hi,yesterday,I took a new BSNL prepaid connection.I have also a vodafone connection.Now,I want to establish call forwarding from vodafone to bsnl,but its showing that Request not completed.Also,when I checked,I noticed that I cannot establish call forwarding from bsnl to vodafone.I have also tried to forward call between 2 bsnl numbers(other one is postpaid),but that has also failed.Please help.

hi,I am an aerospace engineering student of 2nd year.Now I have industrial training at the 4th semester.I want to do the training on communication,navigation and surveillance.Can I do it at kolkata airport or in any other airports in India?

i have a vodafone connection under west bengal circle.when i enter in roaming network,they cut 3 rupees.how can i stop this?please help.

f(x)=sin(logx) and y=f[(2x+3)/(3-2x)]

(1)x^2(x^2-1)dy/dx+x(x^2+1)y=x^2-1

(2)xcos(y/x)(ydx+xdy)=ysin(y/x)(xdy-ydx)

How many orders will be visible if the wavelength of the incident radiation is 5893angstrom and the number of lines on the grating is 2540/inch?

Newton's Rings are observed normally in reflected light of wavelength 5.9*10^-5cm.The diameter of the 10th dark ring is 0.5cm.Find the radius of curvature of the lens and the thickness of the film.

Ultraviolet light of wavelengths 800angstrom and 700angstrom when allowed to fall on hydrogen atoms in their ground state is found to liberate electrons with kinetic energy 1.8eV and 4.0eV respectively.Find the value of Planck's constant
