Step 1: The diagram contains two identical hanging masses m, multiple fixed pulleys and movable pulleys. For each independent ideal string, write one length constraint by summing the lengths of every changing straight segment. Step 2: Each movable mass obeys mg−(sum of its upward supporting tensions)=m a, while the ideal massless pulley marked P requires equality of the resultant upward and downward string forces. Step 3: Different possible interpretations of the low-resolution attachment at th…
