Term
Balance
Definition
ability to control equlibrium
Term
Base of support
Definition
area bound by the outermost regions of contact between a body and support surface / Surfaces
Term
center of mass/gravity
Definition
point around which the mass and weight of a body are balanced , no matter how the body is positioned
Term
couple
Definition
pair of equal , oppositely directed forces that act on oppsite sides of an axis of rotation to produce torque
Term
dynamic equailibrium
Definition
concept indicating a balance between applied forces and inertial forces for a body in motion
Term
first class lever
Definition
lever positioned with the appiled forces and the resistance on oppsite sides of the axis of rotation.
Term
fulcrum
Definition
the point of support , or axis about which a lever maybe made to rotate
Term
lever
Definition
a simple machine consisting of a relatively rigid barlike body that maybe made to rotate about an axis.
Term
mechanical advantage
Definition
ratio of force arm resistance arm for a given lever
Term
moment arm
Definition
shortest (perpendicular) distance between a force's line of action and an axis of rotation
Term
reaction board
Definition
a specially constructed board for determining the center of gravity location of the body positioned on top of it
Term
secound class lever
Definition
lever positioned with the resistance between the applied force and the fulcrum
Term
segmental method
Definition
a procedure for determining total center of mass location based on the masses and center of mass locations of the individual body segments
Term
stabilty
Definition
resistance to distription of equilibrium
Term
third class lever
Definition
lever positioned with the appiled forces between the fulcrum and the resistance .
Term
torque
Definition
the rotary effect of a force about an axis of rotation measured ans the product of the force and the perpendicular distance between the force line of action and the axis.
