Moment theorem of rigid body rotating on fixed axis

Jε=Mo(F) where,

rotary inertia

j=mr^2/2+m 1.r^2+m2.r^2=r^2(m/2+m 1+m2)

Synthetic torque of external force acting on rotating shaft

Mo(F)=gr(m2-m 1sianθ)

Angular acceleration ε = mo (f)/j = gr (m2-m1sianθ)/(r 2 (m/2+m1+m2))

= g(m2-m 1 sianθ)/(r(m/2+m 1+m2))

Acceleration of b

a =εr = g(m2-m 1 sianθ)/(m/2+m 1+m2)

Taking m2 as the research object, Newton's two laws

Square meter = square meter gram ton

Rope tension T=m2.g+am2
