what is the formula to find the young modulus of string?
103361
The above are correct but I think this is more readable:\n\nY = F*L /(dL*A)\n\nY=Young's modulus in units of pressure (F/A)\nF=force\nA=cross-section area\nL=length\ndL=change in length

Erm..... \n\nALT + 465 = ╚\nAlt + 25 = ↓\nALT + 12 = ♀\nALT  + 13 = ♪\nALT + 26 = →\nALT + 21 = §\nALT + 69 = E\n\nI'm just guessing randomised letters with the alt button, Lol. Hope it helps. ( VOTE ME BEST !! ) I gave you the song tune

it is from a logic work sheet.  directions are find the next item in the pattern.  examples:  12321, 23432, 34543, 45654\na, z, b, y, c, x, d\ntam, tan, rib, rid, rat, raw, hip

you can use the isNaN function. If the given text is whole number, then Math.round(n)=n right? So, here is the function\n\nfunction get_type(txt){\nvar type;\nif(!isNaN(txt)){\nvar rnd = Math.round(txt);\nif(rnd==txt){\ntype="wholenumber";\n}\nelse\n{\ntype="decimal";\n}\n}\nelse\n{\ntype="char";\n}\nreturn type\n}\n\nThis function returns "wholenumber" if whole number, "decimal" if decimal, or "char" if character.\n\nHOPE That helps

the explicit formula is related to bernoulli numbers

The frequency, f, of a vibrating string of m kg/m and subject to a tension of T Newtons is given by the relation\n\nf=sqrt(T/m)/2/L\n\nHence the frequency is inversely proportional to the length of the string, assuming the tension remains unchanged.\n\nThus the required length of the string is\n40*474/624=30.385 cm.

Youngs modulus = [F/A]/[∆L/L];  The modulus is a property of the material and does not depend on its dimensions,  However, the modulus is used to find the total change in length (∆L) that comes from the pressure (stress) applied (F/A).\n\nThe weight will increase propotionately to the mass ratio and inversely proportional to the square of the distance (in this case the distance from the center of the planet, the radius).  This is from Newton's Law, F = G*m1*m2/r^2  So that factor would be 4/9

Young's modulus, also know as the modulus of elasticity, is a mechanical material property that defines the elastic nature of a material. For example Young's Modulus (E is used as symbol for this property) of steel; E=3x10^7 psi (pounds per square in). You would need to read up a bit on the definitions of stress and strain to understand further, but if we use the simple stiffness equation of a bar: d = (F * l ) / (A * E ) where d is the displacement, l is the bar length, A is its cross-sectional area, and F is the applied force. It is basically telling you how much the bar will stretch if you pull on it.\n\nPoisson's ratio, is also a mechanical material property. It is usually 0.3 - 0.33 for metals. Simply explained it is how much a material shrinks perpendicular to its loading direction. Imagine an elastic band if you strength it, it not only becomes longer, but the strands become thinner; the amount that the strands thin compared to the amount that they stretch is defined by Poisson's Ratio.\n\nThe notion of a datum is completely unrelated to mechanical properties. A datum refers to a reference (on an engineering drawing or 3D model). Its like the origin of a coordiniate system, often used to simplify how the dimensions are drawn on the drawing. A datum is usually given a letter designation like A , On the drawing you would see it as a straight line with the A in a box touching the line.\n\nNot sure if datum geometry is basically the same thing. The only thing I can think of for that is that there could be different types of Datum i.e. a plane, a point, a cylinder, or a sphere (but I have only come across datum planes in my work, but I could imagine the other shapes could be useful under certain situations.)
