Question

Think about the drinking bird at the beginning of this section (Figure 15.20). Although the bird enjoys the theoretical maximum efficiency possible, if left to its own devices over time, the bird will cease "drinking." What are some of the dissipative processes that might cause the bird’s motion to cease?

a) Evaporation of water from the bird's head
b) Friction in the joints of the bird
c) Air resistance on the moving parts
d) All of the above

Answer 1

Some dissipative processes that might cause the drinking bird's motion to cease are evaporation of water, friction in the joints, and air resistance.

Step-by-step explanation:

The dissipative processes that might cause the motion of the drinking bird to cease are a) evaporation of water from the bird's head, b) friction in the joints of the bird, and c) air resistance on the moving parts.
