Chapter 8: Friction
Friction
Friction is a force that resists the
movement of two contacting surfaces
that slide relative to one another. This
force acts tangent to the surface at the
points of contact and is directed so as to
oppose the possible or exist
Chapter 9: Center of Gravity
and Centroid
Center of gravity
To design the structure for supporting
a water tank, we will need to know
the weight of the tank and water as
well as the locations where the
resultant forces representing these
distributed loads
Chapter 9 (9.5) Fluid Pressure
Mechanics is a branch of the physical sciences that is concerned with the state of rest or
motion of bodies that are subjected to the action of forces

Chapter 4: Force System Resultants
Applications
Carpenters often use a hammer in this way to
pull a stubborn nail. Through what sort of
action does the force FH at the handle pull the
nail? How can you mathematically model the
effect of force FH at point
Assume = 700 N and = 560 N.
(a) Express in Cartesian vector form
(b) Express in Cartesian vector form
(c) Determine the magnitude of the projection of the force along the flag pole
(d) Determine the magnitude of the projection of the force along the flag
Chapter 6: Structural Analysis
Scaffolding
An understanding of statics is
critical for predicting and
analyzing possible modes of
failure.
Buckling of slender members in
compression is always a
consideration in structural
analysis.

Chapter 7: Internal Forces
Internal loadings developed in structural
members
Structural Design: need to know the loading acting within the member in order to be sure the
material can resist this loading
Cutting members at internal points reveal internal f
Chapter 10: Moments of Inertia
Applications
Many structural members like beams and columns have cross sectional
shapes like an I, H, C, etc.
Why do they usually not have solid rectangular, square, or circular
cross sectional areas?
What primary property o
