A mechanic needs to replace the motor for a merry-go-round. The merry-go-round should accelerate from rest to 1.5 rad/s in 7.0 s
marta [7]

Answer

given,

initial speed of merry-go-round = 0 rad/s

final speed of merry-go-round = 1.5 rad/s

time = 7 s

Radius of the disk = 6 m

Mass of the merry-go-round = 25000 Kg

Moment of inertia of the disk

I = \dfrac{1}{2}MR^2

I = \dfrac{1}{2}\times 25000\times 6^2

   I = 450000 kg.m²

angular acceleration

\alpha = \dfrac{\omega_f-\omega_0}{t}

\alpha = \dfrac{1.5-0}{7}

\alpha =0.214\ rad/s^2

we know,

\tau= I \alpha

\tau= 450000\times 0.214

\tau=96300\ N.m
