Generating Force

Question 1

Active Component

Answer 1

active component works as an alternating-current circuit in a device, which works to increase the active power, voltage or current
ex. oscillator, transistor or integrated circuit

Question 2

Active insufficiency

Answer 2

occurs when a multi-joint muscle reaches a length where it can no longer apply effective force

Question 3

Convergent arrangement

Answer 3

something to do with how things are arrange due to genetics and our past

Question 4

Hill’s muscle model

Answer 4

Hill’s muscle model is a graph comparing the acts of active and passive twitch forces to the length of the muscle and determining how the two make the most amount of force

Question 5

Plyometrics

Answer 5

“jump training” exercises in which the muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-stength)

Question 6

Shear

Answer 6

something about deformations and stress

Question 7

Stretch-Shortening cycle

Answer 7

an eccentric contraction followed by an immediate concentric contraction

Question 8

Sub-acute

Answer 8

between acute and chronic

Question 9

Acute vs. Chronic

Answer 9

Acute conditions are severe and sudden in onset. This could describe anything from a broken bone to an asthma attack. A chronic condition, by contrast is a long-developing syndrome, such as osteoporosis or asthma

Question 10

Yield point

Answer 10

A yield strength or yield point is the material property defined as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed

Question 11

What are the mechanical functions of the skeletal system? What about the muscular system?

Answer 11

Skeletal System: support
provides structural support for the entire body

protection
surrounds soft tissue- ex. ribs and sternum protect the heart and lungs, - skull protects the brain

movement
skeletal muscle is attached to bone so it pulls on the bone when it contracts

mineral homeostasis
stores calcium and phosphorus–minerals are released into the blood when needed

blood cell production
red bone marrow produces red blood cells, white blood cells and other blood elements

storage
storage of minerals and lipids(fats)—yellow marrow stores fat –(found in long bones)

Muscular System: movement (muscles attach to the bones to produce force and movement)

Stabilization
to stabilize the body and project it from damage

Question 12

What type of stress is bone strongest in resisting? What type of stress is bone weakest in resisting?

Answer 12

The bone is strongest in resisting stress that is applied on the distal and proximal ends of the bone (long bones) and is least able to resist stress horizontally along the bone’s diaphysis
