All surface are frictionless, strings and pulley are light. If acceleration of block A is a, then acceleration of block B can be represented by Na, then find N.

Answer:

Solution:

For block A (4 kg): $2 T = 4 a$ ; for block C (2 kg): $2 T = 2 a_{C}$ , giving $a_{C} = 2 a$

String constraint (virtual work): $2 T a + 2 T a_{C} - T a_{B} = 0$

$a_{B} = 2 a + 2 (2 a) = 6 a$ , so $N = 6$
