CATERINCA

Recommended Posts

Se dau:

 

- una bucata sistem 5.1 destul de neam-prost de felul lui, care face vibromasaj la picioare

- una bucata biblioteca cu vitrina cu geamuri

 

Geamurile vibreaza profund la peste 50% din volumul dracoveniei. Intrebare: ce frecventa de rezonanta are sticla, ca sa gasesc o melodie cu ritm adecvat si sa le sparg odata, ca sa scap de zbarnaielile geamurilor !

Nu e mai simplu sa dai cu un ciocan, piatra, etc in ele? :mrgreen:

Ai putea sa incerci cu un generator de ton, ii gasesti frecventa, dai sinus si..voila :D

Nu vreau cu ciocanul, e prea primitiv. Vreau inginereste :D

 

E o idee cu generatorul, cred ca pot scoate din calculator semnalul, dar cam in jur de ce frecventa se sparg ? joase sau inalte ?

 

Aia la Mythbusters cand au spart paharele, parca au folosit ceva frecventa inalta. Poate-mi omor din greseala pisica :-?

Ok...

 

Faci o catapulta...nu prea mare cat sa tina max 10 kg(nu cred sa fie mai grea...) adaugi si pisisca in ecuatie...centrezi catapulta spre geam...si tai sfoara...asta in prealabil dupa ce ai calculat distanta, frecarea cu aerul, si nu in ultimul rand sansele de supravietuire ale pisicii.

 

 

Ce zici acu e inginereste? :mrgreen:

Ar merge, dar sunt niste tampenii de fier ornamentale care sustin geamul, si nu cred ca trece pisica printre zabrelele alea.

Faci asa cum a zis uskt cu catapulta, insa amplasezi la o distanta de 0.4-0.5 metri de geam o plasa de pescuit cu ochiuri mici, bine intinsa. Pisica va lovi plasa, se va rupe in bucatele mici care vor lovi geamul si-l va sparge, lasand intacta reteaua metalica din jurul geamului. E ok asa? :-S

O parere total neinginereasca ar fi ca vibreaza la frecvente joase, cu o oarecare amplitutine. Eu as incerca undeva de la 50 Hz in sus, ca sa nu omor nici boxele si nici sa i se faca rau pisicii :D

..... si nici sa i se faca rau pisicii :D

 

Nu mai are cum sa i se faca rau...e deja bucatele...

Vaxxi ia fugi pana acasa sa vezi daca am dreptate ...si in cazul in care am...iti dau eu niste instructiuni sa completezi un puzzle < ;) 48000000.gif

On the Metro I was introduced to "pushers". These were very different from the pushers I knew from the New York City subway. These pushers dressed in uniforms, almost like police, and wore white gloves. At the platform, everyone lined up according to marks on the floor, in double file, one line on either side of the subway car door. When the subway train arrived, it stopped exactly on its mark, the doors opened, and a stream of people poured out between the two lines of awaiting travelers. Once the car had expunged its passengers, the two lines of people would stream into the car. As the car became full, the pushers went to work. They would gently, and very politely, push you further into the car, and push the next person in behind you. When the car was nearly fully to overflowing, the pushers would push the next person in, keeping their hand firmly on the back of the last passenger until the doors started to close. Just as the door was about to close on their arm, the pusher would pull their arm out. Not unlike the way my wife packs a suitcase.

 

As you can imagine, the Metro trains are crammed with people. At one point, two of us missed a stop because we were pushed to the middle of the car, pinned in the crowd, and unable to make our way to the doors for our stop. Of course, I never felt claustrophobic in the subway cars; most of my American coworkers were over 6 feet (1.8m) tall and their heads poked up above the crowd.

Aia la Mythbusters cand au spart paharele, parca au folosit ceva frecventa inalta. Poate-mi omor din greseala pisica :-?

Pentru ca un pahar sa poata fi spart de vocea unei soprane aceasta trebuie sa ajunga la o frecventa cuprinsa intre 700 si 1700 Hz. Cit despre intensitate, se stie ca vocea marilor cintareti poate sa atinga 200 decibeli, adica e suficient de puternica pentru a face un pahar sa vibreze sau chiar sa se sparga. Distrugerea mai depinde insa si de caldura, umiditatea aerului ambiant, de natura suportului pe care paharul se afla asezat si de distanta fata de sursa de emisie sonora. Aceste conditii respectate, orice pahar poate fi spart prin emisia unui sunet.

556 Hz, 105 db au fost "datele" de la Mythbusters, http://www.youtube.com/watch?v=PMg_nd-O688...feature=related

Aha, excelent. Deci sa generez un 556 Hz.

 

Gata. Cine are chef sa incerce, e wave-ul atasat :) Pisica e foarte enervata de zgomot, 556 Hz scoate sigur sistemul, acum sa vedem daca obtin aia 105 db.
