Problem 15E

Atwood’s Machine. A 15.0-kg load of bricks hangs from one end of a rope that passes over a small, frictionless pulley. A 28.0-kg counterweight is suspended from the other end of the rope as shown in (Fig. E5.15). The system is released from rest.

(a)  Draw two free-body diagrams, one for the load of bricks and one for the counterweight.

(b)  What is the magnitude of the upward acceleration of the load of bricks?

(c)  What is the tension in the rope while the load is moving? How does the tension compare to the weight of the load of bricks? To the weight of the counterweight?

Step-by-Step Solution:

Step 1 of 3

(a) The free body diagram can be drawn as shown below.
