    Automotive Symmetrical vs Asymmetrical AWD at high speeds

    thanks for the explanation. so in conclusion, all wheels spin at the same rate despite different amount of torque is being applied to each wheel?

    Automotive Symmetrical vs Asymmetrical AWD at high speeds

    Let's say we have two identical cars (power, weight, drag etc.), the only difference being in the torque split between the front and rear wheels. One has a 50:50 split while the other has a 40:60 split torque distribution. Is symmetrical AWD more efficient at acceleration during high speed...

    How Do You Calculate the Molecular Formula of a Gas Compound in Stoichiometry?

    Ya I know, I have found the molecular weight, but how do i find the empirical weight? isn't it just 0.596g as given? 0.596/23.63?

    Stoichiometry: confused about the question

    Homework Statement a 4.22g mixture of CaCl2 and NaCl was dissolved, and then treated to precipitate all of the Ca as CaCO3, which was then heated to drive off CO2, leaving a sample of pure CaO which was found to weigh 0.969g. What percentage of the original mixture was CaCl[/SUB]2[/SUB]? I...

    How Do You Calculate the Molecular Formula of a Gas Compound in Stoichiometry?

    Homework Statement a sample of gas compound is made up only of B and H weighing 0.596g occupies 484 mL at STP. *then burned in excess O2, it yields 1.17g of H2O and all of the boron is converted to B2O3 what is a) its empirical formula? b) its molecular weight? c) its molecular formula? d)...

    Mathematical Economics, Minimization

    im guessing i can make a1p = S and a2p = (1 - S) then i would get y = [a1pLp + a2pKp]1/p y = [(a1L)p + (a2K)p]1/p

    Mathematical Economics, Minimization

    because my prof said it would be easier if we let a1 = S1/p and a2 = (1-S)1/p and leave our answers in terms of a1 and a2

    Mathematical Economics, Minimization

    Homework Statement Consider the following general form of a constant elasticity of substitution production function: y = [SLp + (1 - S)Kp]1/p Assume a firm is trying to minimize the cost of producing any given y. Cost are given by C = wL + rK Find the firm's cost minimizing demand...

    Solving Jacobi Matrices: Finding Det H6

    Homework Statement An n x n array Hn = (hij) is said to be a jacobi matrix if hij = 0 whenever |i - j| >= 2. Suppose Hn also has the property that for each index i, hii = a, hi, i+1 = b and hi,i-1 = c. For instance, H4 = a b 0 0 c a b 0 0 c a b 0 0 c a (i) Show that det Hn = a (det Hn-1) -...

    Determining Values for a Given Matrix - How Can I Simplify This Process?

    ya sorry, i realized and i did it again, i got x = 3 and -1. my bad, it must be getting late

    Determining Values for a Given Matrix - How Can I Simplify This Process?

    a11a22a33 - a11a23a32 - a12a21a33 + a12a23a31 + a13a21a32 - a13a22a31 = 0 it gets really messy with like = x^3 - 11x^2 + 55x - 93

    Determining Values for a Given Matrix - How Can I Simplify This Process?

    you mean the one the one where you the multiply the diagonals and the subtract it by the other diagonals? in other words (x+5) 4 4 -4 (x-3) -4 -4 -4 (x-3) ------------ (x+5) 4 4 -4 (x-3) -4

    Determining Values for a Given Matrix - How Can I Simplify This Process?

    Homework Statement detA = 0 Matrix A = | (x+5) 4 4 | | -4 (x-3) -4 | | -4 -4 (x-3)| The Attempt at a Solution I know that if one row or column is equal to another, then detA = 0, so using the last 2 rows, i can find out that...
