Izibonelo ezi-5 ze-modulus kaYoung yezinkinga zokucindezeleka nokuqina kokuqina
1. Intambo ye-nylon engu-2 mm ububanzi idonswa ngamandla angama-Newton ayi-100. Thola ukucindezeleka entanjeni!
Ingxoxo
I-Diketahui :
Amandla okudonsa (F) = 100 Newton
Ububanzi bentambo (d) = 2 mm = 0,002 amamitha
Irediyasi yentambo (r) = 1 mm = 0,001 imitha
Kubuziwe : Ukucindezeleka kwentambo
Jawab :
Indawo enqamula intambo :
Ukuqina kwentambo :
2. Intambo enobude bokuqala obuyi-100 cm iyadonswa kuze kube yilapho intambo ikhula ngo-2 mm. Thola ukuqina kwentambo!

Ukucindezeleka kwentambo :
3. Intambo enobubanzi obungu-4 mm kanye nobude bokuqala obungamamitha amabili idonswa ngamandla angama-Newton angu-200 kuze kube yilapho ubude bentambo bushintsha bube amamitha angu-2,02. Bala (a) ukucindezeleka entanjeni (b) ukucindezeleka entanjeni (c) I-modulus kaYoung yokuqina!

I-Diketahui :
Kubuziwe : (a) Ukucindezeleka (b) Ukucindezeleka (c) I-Young's Modulus
Jawab :
(A) Tegangan
(b) Ukucindezeleka
(c) I-modulus kaYoung
4. Intambo ye-nylon enobubanzi obungu-1 cm kanye nobude bokuqala obungamamitha amabili ithola ukudonswa kwama-Newton angu-200. Bala ukwanda kobude bentambo! I-nylon engu-E = 5 x 109 N / m2
Ingxoxo
I-Diketahui :
Kubuziwe : Ukwanda kobude
Jawab :
Ifomula ye-Young's Modulus :
Ukwanda kobude be-nylon :
Ukwanda kobude bentambo ye-nylon = 0,26 millimeters
5. Insika yekhonkrithi inokuphakama kwamamitha ama-5 kanye nendawo enqamulayo engamamitha ama-33 isekela umthwalo ongu-30.000 kg. Bala (a) ukucindezeleka enqwabeni (b) ubunzima enqwabeni (c) ushintsho ekuphakameni kwenqwabeni! Sebenzisa u-g = 10 m/s2. Imodulus kaYoung yokunwebeka kwekhonkrithi = 20 x 109 N / m2

I-Diketahui :
Kubuziwe : (a) Ukucindezeleka kwenqwaba (b) Ukucindezeleka kwenqwaba (c) Ushintsho ekuphakameni kwenqwaba!
Jawab :
(A) Ukucindezeleka kwepole
(b) Ukucindezeleka kwe-pole
(c) Izinguquko ekuphakameni kwesigxobo
Induku isibe mfushane ngamamilimitha angu-0,025.
