1.
When
using the equilibrium of torque formula you
use the length of the fixed effort arm and fixed
resistance arm?
2.
Benedetti
discovered that the length of the effective
effort or resistance arm was the perpendicular
distance from their direction of application
back to the fulcrum.

The
abridged definition of the study of biomechanics
is:
A. Study of forces acting upon, produced by
and then impacting within the musculo-skeletal
system
B. Study of the muscles acting upon the musculo-skeletal
system
C. Study of the forces produced by muscles acting
upon musculoskeletal system
D. Study of the forces impacting the joints
of the musculo-skeletal system
4.
The
effective lever arm was first written about
by:
A. Leonardo da Vinci
B. Borelli
C. Benedetti
D. Archimedes
5.
In
the study of leverage, forces acting on a solid
piece of matter such as a solid bar, the word
used to represent the solid piece of matter
is:
A. Fixed
B. Rigid
C. Steel
D. Immovable
6.
A
simple lever system consists two opposing forces
acting on a solid bar that would cause the solid
bar to move about a fulcrum. The names applied
to these two opposing forces is:
A. Force of resistance
B. Force of effort
C. Stabilizing Force
D. A and B
7.
When
studying human movement the direction of the
force of resistance can typically follow the
direction of gravity, while the force of effort:
A. Follows direction of force of gravity
B. Will be in opposite direction of force of
gravity
C. Will change as the direction of pull of the
muscle changes
D. None of above
8.
The
fixed resistance arm length is:
A. The distance from the from the force of effort
and the force of resistance
B. The distance from the fulcrum to farthest
point on the fixed lever
C. The distance from the fulcrum to the point
on the fixed lever arm that the force of resistance
is applied
D. The distance from the line of gravity to
the fulcrum
9.
The
point at which a muscle insertion attaches to
bone would typically be the length of the:
A. Fixed resistance arm
B. The magnitude of the effort
C. The fixed effort arm
D. Length of the resistance lifted
10.
Modern
day teaching of the 3 classes of lever systems
is based on:
A. The point which force of resistance is applied
to the fixed lever arm
B. The distance from the point of application
of the force of effort and the force of resistance
to the fulcrum
C. The perpindicular distance from the direction
of the force of effort back to the fulcrum
D. A and B
11.
We
advocate that the teaching of the 3 classes
of levers (1st, 2nd, 3rd class) be stopped because
of the following:
A. Physics does not teach them
B. They possess no functional truth
C. They are hard to understand
D. People do not need to know how a lever functions
12.
The physics formula for Equilibrium of Torque
was first discovered by:
A. Archimedes
B. da Vinci
C. Hippocrates
D. Socrates
13.
The
study of muscle force in human movement would
typically be the study of:
A. Force of resistance
B. Force of effort
C. Effective lever arm
D. The fixed effort arm
14.
The study of the anatomical origin and insertion
of muscle and their impact on lever system would
typically be the study of:
A. The force of resistance
B. The force of effort
C. Effective effort arm
D. Fixed effort arm
15.
When lifting a weight and your effective effort
arm length of the muscle is shorter then the
effective resistance arm length of the weight
lifted which of the following is true?
A. Your muscle will not be able to lift the
weight
B. The muscle will have to produce more force
then the force of the weight
C. The weight will produce more force then the
muscle will produce
D. The force that the muscle must produce
will have to be a little less then amount of
force the weight is producing
