Question

please give answer as early as possible​

Answer 1

Answer:

Two wheels of moment of inertia 4 kgm² rotate side by side at the rate of 120 rev / min and 240 rev / min respectively in the opposite directions. If now both the wheels arc coupled by means of weigntless shaft so that both the wheels now rotate with a common angular speed, find the new speed of rotation. (Ans: 60 r.p.m.)

Answer 2

Answer:

180 rev/min

Explanation:

i1w1+i2w2=i3(w1+w2)

4(240+120)=w(8)

w=360/2

w=180 rev/min
