1. A pulley A on the end of a spring balance. On 1 end is a 16kg mass. On the other is pulley B. On one end of pulley B is a mass of 4kg. On the other end is pulley C. On one end of pulley C is a 1kg mass. On the other end is a 7/3kg mass. All pulleys are massless and frictionless. Find accn. of each block 2. Relevant equations 1.Too many pulleys= big confusion! (A very relevant equation here!) Just kidding. Fnet = ma 3. I got the constraint equation as 4a(16) + 2a(4) + a(1) + a(7/3) = 0(no.s in bracket indicate accn. of block of that mass. Now what?
