  • calculus 3 surface integral mathmatics?

    I am getting confused in this subject

    if i was asked to find the surface integral of F.dS

    how do i convert dS in term of dA?

    and how do i convert them to polar coordinates?

    and if i was asked to find the surface integral of F.n.dS

    what is the process to solve them ?

    i looked at websites but they werent helpful at all, and my text book is more useless than ever

    HELP

  • surface integrals mathematics?

    Let S be the surface defined in the following way

    S:= z^2+y^2+x^2=1

    and

    F(x,y,z)= 3*(x^2)*z-2*x*(y^2)

    +2*x*z^2-2*(z^3)+(z^2)

    find the surface integral of(f*dS)

    and

    find the surface integral of( (gradient (f))*dS)

    i got for the first one

    (5/6)*pi

    and the second one

    (-8/3)*pi

    was i right?

  • surface integrals mathematics?

    Hello guys

    I have a question regarding surface integral

    Let S be the surface defined in the following way

    S:= z^2+y^2+x^2=1

    and

    F(x,y,z)= 3*(x^2)*z-2*x*(y^2)+2*x*z^2-2*(z^3)+(z^2)

    Compute analytically the surface integral of

    j=integral (f .dS)

    the way I attempted solving this question is first find the value of dS in terms of dA

    Z=sqrt(1- y^2-x^2)

    dS=sqrt( (x^2)/ (1- y^2-x^2)+ (y^2)/ (1- y^2-x^2) + 1 )dA

    I replaced ever Z of f(x,y,z) with sqrt(1- y^2-x^2)

    My integral becomes integral( F(x,y,z)* sqrt( (x^2)/ (1- y^2-x^2)+ (y^2)/ (1- y^2-x^2) + 1 ))dA

    I changed the integral into polarization form but it keeps growing bigger and bigger.

    What’s the correct method to solve the question

    Thanks

  • Materials science problem?

    A tie‐rod in a BMW M3 needs to support a force of 10.0 kN without yielding. BMW Engineers are considering three different materials for this application; an advanced steel with a yield stress of 600 MPa and density of 7.80 g/cm3, an aluminum alloy with a yield stress of 190 MPa and density of 2.70 g/cm3 and a Mg alloy with a yield stress of 125 MPa and density of 1.74 g/cm3. Which of these materials will result in the lightest tie‐rod that can sustain the above force?

    􁈺Hint: The length of the rod is the same for all materials, but the diameter may be different�.

    in this question the density is messing me up.

    how do i get the stress from the density and the force?

    thanks

  • matrix question what i am doing wrong?

    let A= 1 2 4 -1

    4 0 -1 2

    3 3 7 0

    3 5 6 -4

    given that det A=-4, use the adjoint to find the entry in row 1 column 2 of (inverse A)

    (a) -9/4

    (b) 9

    (c) 9/4

    (d)-65/2

    (e)-9

    i am getting (a) but the proff souloution says its (c)

    where is my mistake

    my solution:

    if it is in row 1 column 2 then i need to find the determinant in row 2 column 1 of A

    | 2 4 -1 |

    | 3 7 0 |

    | 5 6 -4 | = 30-21 = 9

    answer = 9/(-4)

    i cant find my mistake

    For a certain equilibrium reaction Reactants = Products, the standard enthalpy and entropy changes are 123.3 kJ/mol and 219.7 J/K.mol, respectively. Calculate the temperature (in °C, to the nearest degree) above which the Products are favoured, i.e., the equilibrium constant K > 1. Do not use scientific notation. Do not enter units.

    i know that T=deltaH/(DeltaS-RlnK) i know delta H and Delta S but i am not able to figure out the K for this question
