Question 1

What does locomotion have a direct correlation with

Answer 1

Design of muscles and physics

Question 2

How can changing your gate of movement be beneficial

Answer 2

It decreases the cost that you are exerting

Question 3

What is a first class lever

Answer 3

Fulcrum between effort and load

Question 4

What is a second class lever

Answer 4

Load between fulcrum and effort

Question 5

What is a third class lever

Answer 5

Effort between fulcrum and load

Question 6

What types of locomotion require lift and propulsion

Answer 6

Aquatic and aerial

Question 7

What is muscle perfusion

Answer 7

Capillaries bring oxygen to the muscles

Question 8

What can the Krogh model be used for

Answer 8

Estimate oxygen delivery to the muscles

Question 9

What is laminar flow

Answer 9

Fluid flows over surface in smooth layers

Question 10

What is turbulent flow

Answer 10

Fluid flows over surface in a less ordered fashion

Question 11

What is reynolds number

Answer 11

Ratio of inertial forces to viscous forces in a fluid

Question 12

What does a low Reynold number mean

Answer 12

Laminar flow

Question 13

What does a high Reynold number mean

Answer 13

Turbulent flow

Question 14

What is drag

Answer 14

A force that opposes movement

Question 15

What is friction drag

Answer 15

Interaction between surface and fluid

Question 16

What is pressure drag

Answer 16

Force required to redirect fluid around the object

Question 17

Do animals of similar geometry but different sizes move the same distance

Answer 17

Yes bigger animals move their center of gravity higher because it starts higher

Question 18

How does cost of transport change with gaits

Answer 18

By changing the gait you can increase speed without increasing energy expenditure
