Basic Biomechanics With Rationale Qs & As – solution/ A+

Basic Biomechanics With Rationale Qs & As –
solution/ A+

neutral equilibrium - CORRECT ANSWERS-an object's COG is neither raised not
lowered when it is disturbed (ex. a ball rolling or pushing a wheelchair)

static equilibrium - CORRECT ANSWERS-object not in motion; all external forces acting
on a mass is zero (COG is close to BOS)

wider BOS=? - CORRECT ANSWERS-more stability

lower COG=? - CORRECT ANSWERS-more stability

example of first class lever in the body - CORRECT ANSWERS-atlas & axis tilting head

what are first class levers designed for? - CORRECT ANSWERS-balance

point where all planes of the body intersect - CORRECT ANSWERS-center of gravity
(COG)

approaches to intervention - CORRECT ANSWERS-1. restoration/remediation
2. compensate/adapt
3. prevention

adapt - CORRECT ANSWERS-change an activity due to a sustained impairment;
change activity so it can be done; modification

grade - CORRECT ANSWERS-incremental changes to an activity to restore or
remediate function; continue to change over time to address progress

anterior - CORRECT ANSWERS-front

posterior - CORRECT ANSWERS-back

superior - CORRECT ANSWERS-above

inferior - CORRECT ANSWERS-below

flexion - CORRECT ANSWERS-

flexion - CORRECT ANSWERS-

extension - CORRECT ANSWERS-

, extension - CORRECT ANSWERS-

dorsiflexion - CORRECT ANSWERS-

plantar flexion - CORRECT ANSWERS-
torque - CORRECT ANSWERS-a force that causes rotation

compression - CORRECT ANSWERS-A force that pushes on or squeezes a material.

tensile force - CORRECT ANSWERS-force applied in opposite directions to stretch an
object

shear force - CORRECT ANSWERS-twisting/rubbing forces in opposite directions

linear force - CORRECT ANSWERS-two or more forces acting along the same line

compression - CORRECT ANSWERS-

tensile force - CORRECT ANSWERS-

shear force - CORRECT ANSWERS-

linear force - CORRECT ANSWERS-

what happens if two people are using the same magnitude of force when pushing
against the same line? - CORRECT ANSWERS-no movement

parallel force - CORRECT ANSWERS-occur in same plane in same or opposite
directions

parallel force - CORRECT ANSWERS-

in a parallel force, where must the opposite force be located? - CORRECT ANSWERS-
between the two parallel forces

in a parallel force, what happens when all forces are equal? - CORRECT ANSWERS-no
movement (stability)

concurrent forces - CORRECT ANSWERS-Two or more forces acting on a common
point but pulling or pushing in different directions.

concurrent forces - CORRECT ANSWERS-

resultant force - CORRECT ANSWERS-overall effect of the two concurrent forces
