1. The problem statement, all variables and given/known data Find the acceleration of both blocks 2. Relevant equations Dynamics 3. The attempt at a solution Everything in black is given in the problem. The red/blue is my work. First I want to relate the acceleration of block A to block B by finding the constraint equations: Lrope = 2L1 + L2 + 2L3 + constants(lengths around pulleys) taking the derivative twice to find the acceleration: 0 = 2L1 + L2 + 2L3 I feel like I have too many variable here. I should be able to knock it down to two so that I can relate the acceleration of A to B, correct? How would I do that? The forces on B, all in Y using the normal xy-coordinate system. MbAb = 3T - Mb(g) The forces on A, using a coordinate system along the incline where n1 is "up" and n2 is positive along the slope DOWN: Sum of the forces in n1 = ma(n1) = Na - mgCos30 Sum of the foces in n2 = ma(n2) = -2T - Fa + mgSin30 Relating the two coordinate systems: n1 = Cos 30 j - Sin30 i n2 = -sin30 j - cos30 i Have I done everything correctly so far?
