with complete solution
the forces exerted by your hand on a screw driver is an example of a
force couple system
improper constraint implies...
non equilibrium and instability
statically determinate
body is supported by a minimum number of constraints to ensure equilibrium
statically indeterminate
to have more constraints than required
True or False...Improper constraint implies there are more unknown loads and/or
support reactions than equations of equilibrium
True
True or False... Improper constraint implies the body is under load and all reactive
forces are concurrent or parallel
true
True or false... Improper constraint implies the body is under load and support reactions
DO NOT intersect a common axis
False
True or false...Improper constraint implies a body is improperly constrained if it is
partially constrained
True
Moment of a force causes a body to...
rotate around a point
moment sense of rotation direction is determined by...
the right hand rule
Magnitude of a moment equation:
moment = force x distance = scalar
Resultant moment is...
sum of moments caused by multiple forces acting on a body
pure moment
a force that causes only rotation of a body
True or False... A pure moment is a vector quantity
True
True or False... A force couple has zero resultant force
True
True or False... A force couple exerts different resultant moments about all points on r
False
True or false... the drag forces acting on a spinning propeller is an example of a force
couple system
True
Moments appear as (internal/external) forces in structural members or components
internal
An example of an engineering system that exerts torque is...
