Question

Two crates A and B shown are supported by an inextensible cable on frictionless and massless pulleys. The mass of the heavier crate A is 37 kg. when free to move, the acceleration of A with respect to B, aA/B = 6m/s/s. Determine the mass of crate B in kg.

The pulley shown in P9 is supported by a single chain at C. Determine the tension in this chain in N when the two crates described in P9 are free to move.

Step 1

Both the crates are free to move with a same cable, the acceleration of the both crates are same magnitude with opposite direction. Consider the acceleration of the both crates be *a*.

From the relative acceleration, the acceleration of the crates can be calculated as,

Step 2

Apply the Newton’s second law on the crate *A.*

Step 3

Apply the Newton’s second la...
