Homework Statement Calculate dhkl and vc for the (111) direction of germanium. Homework Equations dhkl=a/sqrt(h2+k2+l2) vc=unit cell volume=a1dot(a2xa3) or vc=structure form factor/density The Attempt at a Solution dhkl=a/sqrt(3) I know how to solve this, I've just...

Thanks for your help!

Homework Statement B=1/(1+(1/1+(1/1+(1/1+(1/1+... what does B equal? Homework Equations I don't believe there are any...it's a conceptual question. The Attempt at a Solution Would it converge to 0? My reasoning was that if 1/(1+1)=1/2, and then 1/(1+1/2)=1/(3/2)=2/3, and...

From what I have read it's MAC=LAC/density...I just want to confirm this is correct. Thanks!

So tension in the red rope would equal 1/3(W+B), and then tension in the green rope would equal 1/3(A+1/3(W+B)) ?

Homework Statement We are asked to find the force (F) needed to maintain equilibrium. I've drawn a picture; the red, blue, and green ropes are three separate ropes. Block W has a weight of 500 lbs, pulley A has a weight of 10 lbs, and pulley B has a weight of 20 lbs. the picture...

Homework Statement I'm building a hovercraft, and I'm familiar with how to calculate center of mass--however, there's something that will be sitting on the surface of the hovercraft that's throwing me off. I just can't seem to get it to work. I'm just trying to find what the mass would be at...
