Question

A flywheel starting from rest is accelerated by a steady torque of 24 Nm so that it acquires an angular velocity of 6 rad/s after 2 seconds. The mass of the fly wheel is 15 kg. Calculate angular acceleration and radius of gyration​

Answer 1

Explanation:Angular acceleration α= Angular acceleration α= 8Angular acceleration α= 824Angular acceleration α= 824Angular acceleration α= 824 =3rad/s Angular acceleration α= 824 =3rad/s 2Angular acceleration α= 824 =3rad/s 2 Angular acceleration α= 824 =3rad/s 2 Now angular displacement θ=0+ Angular acceleration α= 824 =3rad/s 2 Now angular displacement θ=0+ 2Angular acceleration α= 824 =3rad/s 2 Now angular displacement θ=0+ 2αt Angular acceleration α= 824 =3rad/s 2 Now angular displacement θ=0+ 2αt 2Angular acceleration α= 824 =3rad/s 2 Now angular displacement θ=0+ 2αt 2 Angular acceleration α= 824 =3rad/s 2 Now angular displacement θ=0+ 2αt 2 Angular acceleration α= 824 =3rad/s 2 Now angular displacement θ=0+ 2αt 2 =96rad
