6. what is statics ?
Statics is the branch of mechanics that is concerned
with the analysis of loads (force and torque, or
"moment") acting on physical systems that do not
experience an acceleration (a=0), but rather, are in
static equilibrium with their environment.
7. a force is an interaction that causes an affected object to be pushed or
pulled in a certain direction. A force is always a push, pull, or a twist, and
it affects objects by pushing them up, pulling them down, pushing them
to a side, or by changing their motion or shape in some other way
Force
8. A condition in which all influences acting cancel each
other, so that a static or balanced situation results. In
physics,equilibrium results from the cancellation of
forces acting on an object.
Equilibrium
9. Structural analysis is the determination of
the effects of loads on
physical structures and their
components. Structuressubject to this type
of analysis include all that must withstand
loads, such as buildings, bridges, vehicles,
furniture, attire, soil strata, prostheses and
biological tissue.
Structural Analysis
11. Friction is the force resisting the relative
motion of solid surfaces, fluid layers, and
material elements sliding against each
other. There are several types offriction:
Dry friction is a force that opposes the
relative lateral motion of two solid surfaces
in contact.
Friction
13. The centroid of a triangle is the intersection
of the three medians of the triangle (each
median connecting a vertex with the
midpoint of the opposite side). It lies on the
triangle's Euler line, which also goes
through various other key points including
the orthocenter and the circumcenter.
Centroid
15. The amount of torque needed to cause any
given angular acceleration (the rate of
change in angular velocity) is proportional
to the moment of inertia of the body. ... For
a point-like mass, the moment of
inertia about some axis is given by , where
is the distance of the point from the axis,
and is the mass.
