Tsarin ƙwayoyin cuta - matsaloli da mafita

1. Abu A mai nauyin kilogiram 6 da abu B tare da a taro na kilogiram 4 da aka haɗa ta hanyar igiya kuma aka ja ta da ƙarfin F = 60 N, kamar yadda aka nuna a cikin hoton da ke ƙasa. gogayya ta motsi Tsakanin bene da abubuwa biyu shine 0.5 (tan θ = ¾). Hanzarta saboda nauyi shine 10 m/s²Menene girman ƙarfin tashin hankali?

An sani:

Nauyin abu A (m)_A) = 6 kg

Nauyin abu B (m)_B) = 4 kg

Ƙarfi (F) = 60 Newton

Kiyaye makamashin injiniya a saman lanƙwasa - matsaloli da mafita

1. Idan gudun ƙwallon a wurin A shine 6 m/s, gudun ƙwallon a wurin B shine √92 m/s, kuma hanzari saboda nauyi shine g = 10 m/s²Menene tsayin maki B (h)?

An sani:

Gudun ƙwallo a aya ta A (v_A) = 6 m/s

Gudun ƙwallo a aya ta B (v_B) = √92 m/s

Saurin gudu saboda nauyi (g) = 10 m/s²

Tsayin A (h)_A) = mita 5.6

Cibiyar nauyi - matsaloli da mafita

1. Ƙayyade daidaitattun abubuwan tsakiyar nauyi na abin kamar yadda aka nuna a cikin hoton da ke ƙasa.

Magani:

Raba abin zuwa sassa uku.

Yankin sashi na 1 (A)₁) = (2)(6) = 12 cm²

Ma'aunin tsakiya yana kan ma'aunin x (x)₁) = 1/2 (2) = 1 cm

Ma'aunin tsakiya yana kan axis y (y)₁) = 1/2 (6) = 3 cm
