The pulley system shown is used to hoist the 265-kg block. The diameter of the bearing for the upper pulley is 21 mm, and that for the lower pulley is 12 mm. For a coefficient of friction = 0.17 for both bearings, calculate the tensions T, T₁, and T₂ in the three cables if the block is being raised slowly. 196 mm- T T₂ 265 kg T₁ 98 mm Answers: T = i T₁ = T2= i Mi N N N The pulley system shown is used to hoist the 265-kg block.
