On the right paragraph it says "The trial divisor 1200 goes into the dividend 13952, 8 times" Clearly 1200 goes into 13952, 11 times. I don't understand why 8 is (arbitrarily?) chosen. Please help. Thanks.

i see. So the original 2600 mah is the actual capacity, and the "C" is the maximum amount of charge you can get from the battery, provided it still is limited by that original 2600 mah limit.

so I could draw 13000 ma for one hour? But it said originally 2600 ma for one hour. I'm confused about this. thx

discharge. this isn't an actual battery, just roughly of the things I'm seeing. I need to know what they mean. Its discharge.

A battery is rated as follows: 2600 mah 12 V 5C My question is what does each of these values mean? 2600 mah is the "capacity" of the battery. To my understanding this means you can draw 2600 ma current from this battery for exactly one hour; after one hour the battery is dead. Or you can...

Homework Statement Total enthalpy is defined such that: h+(V^2)/2 = constant ... (1) h0 is the stagnation enthalpy. Stagnation means V=0. Plug this V into the above, get h=h0. Hence h+(V^2)/2 = h0 ... (2) My question is we already defined V=0, so how could there still be a V^2/2 term in...

Homework Statement Find D2/D1. See attachment. Homework Equations The Attempt at a Solution Ans: D2/D1 = 0.68 I can't figure this one out. Any special trigonometric identities that might help here? Thanks.

Homework Statement Define Force in a system of particles about point P Homework Equations The Attempt at a Solution I know force can be explained but not defined. However, i don't think you can just say the force is a push or a pull in a "system of particles about point P". Can...

Homework Statement See attachment. Homework Equations The Attempt at a Solution Equations (1) and (2) describe this gear train system. I'm confused about them. For (1): If I rewrite it (∑F=0 format) I get: T-T1-Jθ''-Bθ' = 0 The figure clearly shows θ1 positive spinning...

the slope, y/x. Why would dv/dx=0 at x=L/2? That makes no physical sense, because at x=L/2 there is a load P upward and it must deflect. Hence dv/dx can't be 0.

ok, so what is the slope physically mean? Why is it 0 at x=L/2? It has something to do with the load P? I see that the derivative of moment is shear force, and the derivative of shear force is distributed force. But that has nothing to do with deflection right?

Homework Statement Find the deflection at x=L/4 and x=L/2 for the beam Homework Equations See attached pic. The Attempt at a Solution So I have the solution derived in class. Only 0<x<L/2 is derived because since the load on the beam is at L/2, the equation is valid for the...

Homework Statement I'm taking the Laplace transform of F(s), and the first thing is to expand it by partial fraction or something so that I can match F(s) with a table of laplace transforms. Homework Equations The Attempt at a Solution Does partial fraction even work? I've got two...

Homework Statement What (complete) set of sampling and filtering parameters would you choose to record a signal from a high speed pressure sensor if you wanted to accurately determine its power spectrum below 35 kHz with a resolution of 0.5 Hz? Homework Equations frequency resolution =...

Homework Statement One mole of CO and 1/2 mole of oxygen are mixed and the products consist of CO2, CO, O2, and O. Write the atom balance for C and O. Homework Equations Mass conservation The Attempt at a Solution 1/2(O2)+CO2 -> aCO2 +bCO+cO2 +dO. a, b, c, d are unknowns. I make a table...
