Two blocks are attached by strings of negligible mass to a pulley with two radii R1=0.29 m and R2=0.69 m. The strings are wrapped around their respective radii so that the blocks can move either up or down. The pulley has a moment of inertia about its center I=0.221 kg⋅m2, and is supported by a bearing with negligible friction. If block 1 has a mass of 2.9 kg and block 2 has a mass of 0.42 kg, what is the magnitude of the angular acceleration of the pulley?

Step 1

Given values:

R1 = 0.29 m

R2  = 0.69 m

Moment of inertia of the pulley, I = 0.221 Kg m2

M1 = 2.9 kg

M2 = 0.42 kg

Step 2

We know, The torque:

Step 3

Moment of inertia of...
