Physics

[Smith Rowe]

A hollow cylinder of radius 100cm rotates about its axis which is vertical. A small body remain in contact with inner wall.
If the frequency of rotation is 180 per minutes.

i) Coefficient of friction between the body and the cylinder

ii) Frictional force between the body and cylinder if the mass of the body is 50gram

Formula ya moment of inertia haipo kichwani tena

 

[Baba Swalehe]

Source ya centripetal force ni static friction

Ambayo formula yake ni = uR , u ni coefficient of static friction na R ni mg

Haya substitute kwamba uR ni sawa na mw²r nadhan hyo w ( angular velocit unajua jins ya kuitumia )

W ni sawa na 2pie over T ambay ni sawa na kusema 2pie frequency

Nimeitwa kazn siwez kuandk sa hvi

Kitu kikiwa kwenye cylinder ili kiendelee kubaki

Centrifugal force ambayo ni opposite ya centripetal lazima ibalance na friction static force basi mchez umeisha nmekuelekeza hapo chin

 

[Voxwiser]

Hapo una times 7 then unaimanupulate na 65%8 then unaigawa kwa yenyewe

Daaahh, umeanza kurejesha mafaili yangu.

Phyz bana, concept ndio inazaa formula, mwisho unapachika tu midata...

Ebu nikumbushe kuhusu senzota....

[emoji28]dogo alete mawe ya kina muncaster

Kuna swali muncaster mpaka kesho nalifikiriaga

Sijui alitunga akiwa uchi lile swali

Formula zote znagoma zoote ani

Nalkumbukaga sana lile swali

 

[Tychob]

Pond boy, mwalimu wa physics wenu alikuwa nani?

Ebu nikumbushe kuhusu senzota....

 

[Baba Swalehe]

Hujasahau ha ha ha

Teh ..

Acha tumsaidie mdg etu

Asiende kule kwenye siasa akakutana na madhila ya kina faiza foxy

Nimemkumbuka aisee.

Alikuwepo mwingine alikuwa anaitwa Makoba(alikuwa afundisha kama vile mtu ambaye anajikumbusha kitu alichokisahau kwa muda mrefu)

Mwingine alikuwa anaitwa Babwanga. Hawa walikuwa wanafundisha PCB
