Given: mechanism consists of 3 members: (1) homogeneous disk 1 of mass m1=13kg and radius R1=26cm; (2) nonhomogeneous disk 2 of mass m2=17kg, bigger radius R2=51cm, smaller radius r2=33cm, radius of inertia ρ2=42cm; (3) block 3 of mass m3=29kg.
Mechanism is moving in vertical plane from the state of rest under the action of gravity forces.
Find: absolute value of acceleration of block 3 (in m/s2) a3=?
