1. The problem statement, all variables and given/known data dynamic viscosity 1 = 1125 2 kgf-s / m2 , dynamic viscosity 2 = 62.5 2 kgf-s / m2 , Areas: A1 = 20 cm2 , A2 = 50 cm2 W1 = 15 Kgf, W2 = 40 Kgf. The block (2) is displaced downwards with a constant speed of 80 mm / sec, whereas linear velocity distribution determined: 1) The weight of the block (3). 2) The speed of the block (1). Neglect friction in the pulley 2. Relevant equations the angle is 30º (tangencial force) / area = (dynamic viscosity) (velocity/space betwteen the two surfaces) sum forces=0 (Equilibrium) 3. The attempt at a solution I did the problem of two ways, considering each block and considering the system, but I dont get the same answer. What am I doing wrong??
