Ukunyakaza okufanayo esindilinga esivundlile - izinkinga nezixazululo

1. Ibhola elingamakhilogremu angu-0.2, elinamathiselwe ekugcineni kwentambo evundlile, lizungezwe yindilinga yerediyasi engu-1 imitha kanti isivinini esiphezulu sebhola singama-10 rpm. Ubukhulu balo buyini? ukusheshisa okuphakathi kanye nobukhulu bamandla okucindezela?

Kwaziwa:

Imisa (m) = 0.2 kg

Irediyasi (r) = 1 m

I-angular velocity (ω) = 10 rev/min = 10 rev/60 s = 0.17 rev/s = (0.17)(6.28 rad)/s = 1 rad/s

Velocity (v) = r ω = (1 m)(1 rad/s) = 1 m/s

Kufunwa: a_s dan ΣF

Isixazululo:

(a) Ubukhulu bokusheshisa kwe-centripetal

(b) Ubukhulu bamandla okucindezela

ΣF = ma

T = ma_s

T = (0.2 kg)(1 m/s²)

T = 0.2 kg m/s²

T = 0.2 N

2. Ibhola elingamakhilogremu angu-1 ekugcineni kwentambo lijikeleza ngokulinganayo esiyingini esivundlile esingu-1 m. Intambo izophuka uma ukucindezeleka okukuyo kudlula ama-N angu-100. Yiliphi ijubane elikhulu ibhola elingaba nalo?

Kwaziwa:

Isisindo (m) = 1 kg

Irediyasi (r) = 1 imitha

Amandla okucindezela (T) = amandla centripetal (ΣF) = 100 N

Okufunayo: ubukhulu be-v

Isixazululo:
