Isihloko mayelana Iziphethu zilandelana futhi zihambisana
1. Iziphethu ochungechungeni
Uma intwasahlobo ixhunywe ngochungechunge, njengasesithombeni ohlangothini, khona-ke:
1. Ukwanda kobude bentwasahlobo = ukwanda kobude 1 + ukwanda kobude 2
Δ y = Δ y 1 + Δ y 1
2. Amandla atholakala entwasahlobo elinganayo = amandla atholakala entwasahlobo 1 = amandla atholakala entwasahlobo 2
F s = F 1 = F 2
3. I-constant yentwasahlobo efanayo ( ks )
1/k s = 1/k 1 + 1/k 2
Inkinga yesampula 1:
Iziphethu ezimbili ezifanayo ngasinye sinokuqina okungu-100 N/m okuxhunywe ochungechungeni. Uma ukuhlelwa kwesiphethu kunikezwa umthwalo ukuze wande ngo-4 cm ubude, khona-ke ukwanda kobude besiphethu ngasinye ku ...
Isixazululo:
Ukwanda okuphelele kobude beziphethu ezimbili kungu-4 cm, ngakho-ke ukwanda kobude besiphethu ngasinye kungu-2 cm.
2. Iziphethu zihambisana
Uma intwasahlobo ixhunywe ngokufana, njengasesithombeni ohlangothini, khona-ke:
1. Ukwanda kobude bentwasahlobo elinganayo = ukwanda kobude bentwasahlobo 1 = ukwanda kobude bentwasahlobo 2
Δ y = Δ y 1 + Δ y 1
2. Amandla atholakala entwasahlobo efanayo = amandla atholakala entwasahlobo 1 + amandla atholakala entwasahlobo 2
F s = F 1 + F 2
3. I-constant yesintwasahlobo efanayo (k p )
kp = k 1 + k 2
Inkinga yesampula 2:
Iziphethu ezimbili ngasinye esino-c ongaguquki ohlelwe ngokulingana. I -spring engaguquki yalolu hlelo iba …
Isixazululo:
Isilinganiso esilinganayo sentwasahlobo (k p ) = c + c = 2c
