Ok.. that's what i wanted to hear.. I wanted to get confirmation from someone that simplifying the torque analysis by saying all forces act through the CM is no longer valid in this case. Thank you

my work based on your angle definition well.. i have calculated the net torque based on the way you defined theta and phi... i don't see how the general expression goes to zero...

Yes, and the net torque according to my work for sub critical angles does not absolutey go to zero... and I have not been able to identify what i did wrong... the only explanation to my net Torque not going to zero is for sub critical angle where the flat base is fully in contact with the...

i have defined alpha and theta, so your phi is 90 - alpha. I feel like for sub critical angles, this CM treatment in calculating the net torque may not work. Just like when it is at the critical angle, Fnormal and Ffrictin do not come into play because they are drawn from the pivot point, not...

thank you for your reply. The question is set up such that friction doesn't exist. Also, i took into account the fact that Fn = Fg cos (theta) i don't see what part of my work is wrong because my conclusion for some arbitrary angle less than the critical angle, (when the base is fully in...

Homework Statement I know this tipping a block question has been asked many times and I know how to find the critical angle at which a block tips over. I was just wondering how one would go about analyzing the torque of the system. We all know that anywhere from 0 to the critical angle...

"basic paraxial optics toolkit' seems very useful but its either my lack of knowledge or the way it is designed but I am not sure how to simulate introducing spatially dependent phase between cavity mirrors.

Hello there, I have been searching for MATLAB simulations that analyze optical cavities and there are some useful codes. Yet, I haven't found codes that analyze what happens to cavit transverse modes if spatially dependent phase is introduced between mirrors Does anybody know if there...

i have looked at Microwave Studio and COMSOL. there websites don't seem to sell them.. do you know where i can purchase these products?

Hello everyone. I'm really struggling to simulate a cavity problem. My goal is to be able to know what's going to happen if i introduce spatially dependent phase inbetween mirrors of a cavity that supports certain transverse modes. Well, i believe solving for eigenmodes of a cavity is...

Homework Statement Hello everyone, I was trying to plot (density plot and 3d plot) Hermite Gaussian polynomials on Mathematica hoping the plot will be good enough to show patterns such as this link ...

I have uplloaded the problem statement in the attachment sorry i forgot to mention that

Homework Statement I have proved the first one and I am trying to do the second using the result from part 1) Homework Equations F_1=1, F_2=2, F_n=F_{n-1}+F_{n-2} The Attempt at a Solution base case: F_1|F_k since F_1=1 Assume it works for n, F_n|F_{kn} show F_{n+1}|F_{kn+k}...

Ive been going through some landers of Venus and Mars and I found they were equipped with radio doppler experiment(http://en.wikipedia.org/wiki/Venera_9 ) I was wondering what this does. I mean there is radio signal transmitted through space everywhere and i suppose the device would measure...

questions about the Soviet's Venus missions I was reading about the Soviet Union's Venus missions and they equipped Venera 9 orbiter with cherenkov detector. So it detects particles traveling faster than the speed of light in a given medium What was this Cherenkov detector used for? It...
