1. A na-etinye ike F n'ime eriri e ji kechie ihe mkpuchi silinda. torsion is 2 N m na oge nke inertia is 1 kg m2, gịnị bụ angular osooso nke silinda ahụ.

Mgbanwe ntụgharị - nsogbu na ngwọta 1A maara:

Torque (τ) = 2 N m

Oge nke inertia (I) = 1 n'arọ m2

Chọrọ: Ọsọ ọsọ nke silinda ahụ

Ngwọta:

Στ = M α

Στ = net torque, I = oge nke inertia, α = osooso n'akụkụ

Osooso akụkụ nke silinda:

α = Στ / I = 2/1 = 2 rad/s2

2. A na-etinye ike F n'ime eriri e ji kechie ihe mkpuchi silinda. Oke ike ahụ bụ 10 N, radius nke silinda bụ 0.2 m na oge nke inertia bụ 1 kg m2, Wokpu bụ osooso akụkụ nke silinda ahụ?

Mgbanwe ntụgharị - nsogbu na ngwọta 2A maara:

Ike (F) = 10 N

Radius nke silinda (R) = 0.2 m

Oge nke inertia (I) = 1 n'arọ m2

Chọrọ: Ọsọ ọsọ nke silinda ahụ.

Ngwọta:

τ = FR

τ = ike, F = ike, R = radius nke silinda

Torque:

τ = FR = (1)0 N)(0.2 m) = 2 N m

Στ = M α

Στ = net torque, I = oge nke inertia, α = osooso n'akụkụ

Osooso akụkụ nke silinda:

α = Στ / I = 2 / 1 = 2 rad/s2

3. A na-etinye ike F n'ime eriri e ji kechie ihe mkpuchi silinda. Oke ike ahụ bụ 10 N, radius nke silinda bụ 0.2 m na ibu nke silinda bụ 20 kg m2,. Wokpu bụ osooso akụkụ nke silinda ahụ.

Mgbanwe ntụgharị - nsogbu na ngwọta 3A maara:

Ike (F) = 10 N

Radius nke silinda (R) = 0.2 m

Ibu nke silinda (M) = 20 kg

A chọrọ: Osooso akụkụ nke silinda

Ngwọta:

τ = FR = (1)0 N)(0.2 m) = 2 N m

Oge nke inertia:

I = 1/2 MR2 = 1⁄2 (20)(0.2)2 = 1⁄2 (20)(0.04) = 0.4 kg m2

Osooso akụkụ nke silinda:

α = Στ / I = 2 / 0.4 = 5 rad/s2

4. Blọk 1-kg nke e ji eriri kechie gburugburu ihe mkpuchi silinda. Oge inertia nke ihe mkpuchi ahụ bụ 1 kg. m2 na radius nke pulley bụ 0.2 m. Gịnị bụ ọsọ nke pulley ahụ. Ọsọ ọsọ n'ihi ike ndọda bụ 10 m/s2.

Mgbanwe ntụgharị - nsogbu na ngwọta 4A maara:

Oge nke inertia nke pulley (I) = 1 kg m2

Mass nke ngọngọ (m) = 1 kg

Ọsọ ọsọ n'ihi ike ndọda (g) = 10 m/s2

Arọ (w) = mg = (1 kg)(10 m/s2) = 10 kg m/s2 = 10N

Radius nke pulley (R) = 0.2 m

A chọrọ: Osooso akụkụ

Ngwọta:

Torque:

τ = FR = w R = (1)0 N)(0.2 m) = 2 N m

Oge nke inertia:

I = 1 kg m2

Ọsọ ọsọ n'akụkụ:

α = Στ / I = 2 / 1 = 2 rad/s2

5. Blọk 1-kg nke e ji eriri kechie gburugburu ihe mkpuchi silinda. Ibu nke ihe mkpuchi ahụ dị kilogram 20. na radius nke pulley ahụ bụ 0,2 m. Gịnị bụ ọsọ ọsọ nke pulley na akụkụ ya? free-ada osooso nke ngọngọ ahụ. Ọsọ ọsọ nke ike ndọda bụ 10 m/s2.

Mgbanwe ntụgharị - nsogbu na ngwọta 5A maara:

Ibu nke pulley (M) = 20 kg

Radius nke pulley (R) = 0,2 m

Ibu nke blọk (m) = 1 kg

Ọsọ ọsọ n'ihi ike ndọda (g) = 10 m/s2

Ibu (w) = mg = (1 kg)(10 m/s2) = 10 kg m/s2 = 10N

A chọrọ: osooso nkuku nke pulley na osooso n'efu nke blọk ahụ.

Ngwọta:

Ike ike:

τ = FR = w R = (1)0 N)(0.2 m) = 2 N m

Oge nke inertia nke cylinder pulley:

I = 1/2 MR2 = 1⁄2 (20)(0.2)2 = (10)(0.04) = 0.4 kg m2

Ọsọ ọsọ nke pulley:

α = Στ / I = 2 / 0.4 = 5 rad / s2

Ọsọ ọdịda n'efu nke ngọngọ ahụ:

a = R α = (0.2)(5) = 1 m/s2
