ASSUME THAT S/A= 4.5, D/A= 4.5, N/E= .80 AND A=D+E SLOVE FOR N/S.

  • ALGERA - ,

    Well, from the first two, D=S
    and D=4.5A
    From the fourth,
    A=D+E=4.5A+E
    or E=-3.5A
    But N=.8E, so N=.8*(-3.5A)

    solve for N/S is the same as N/D

    N/s=N/D=.8*(-3.5A)/4.5A
    and surely you can finish it.

  • ALGERA - ,

    is -.62 correct

  • ALGERA - ,

    It is if you checked my work and found no errors.
