Question

A 750 kg flywheel of a steam engine having radius of gravitation of .5 m starts from rest with standing torque 1500nm tge angular acceleratorof fly wheel

Answer 1

Answer:

8 rad/s^2

Explanation:

here, Mass of the flywheel, M = 750 kg

Radius of gravitation, K = 0.5 m

The starting torque of the engine is , T = 1500 nm

angular acceleration ⋉ = ?

T = 工.⋉  

   

    =  MK^2.⋉

 

1500 = 750 x (0.5 x0.5) x ⋉  

1500 = 750 x 25 x ⋉  

    ⋉  =   1500/187.5

∴   ⋉  =   8 rad/s^2

Thus, the angular acceleration of the flywheel is 8 rad/s^2.
