SOLVER Approach
• SKETCH diagrams that you
think will be useful in solving
the problem
• OUTLINE the sequence of
solution strategy and steps
• LIST the knowns and
unknowns
• VALUATE i.e. solve the
problem
• EVALUATE if the valuation
results make sense
• REFLECT on the part of the
problem-solving that
presented any difficulty
• Sample of an
Outstanding
Handwritten
Problem
Solution
BEST
PRACTICES
• Box your final
answer
• Follow the sigfig
rules in ES 101
• Don’t forget to
Evaluate and
Reflect!

• What adjective starting with the first letter
of your first name describes you best?
• What’s the best piece of advice you’ve
ever been given?
Mechanics
• The study of forces and its
effects
Engineering Mechanics
• Is both a foundation and
framework for many fields of
engineering
Why Study Engineering Mechanics?
• To develop the capacity to predict the effects of force
and motion while carrying out the creative design
functions of engineering
• To able to visualize physical configurations in terms of
real materials, actual constraints, and practical
limitations
Engineering Mechanics
• deals with the behavior of a body when the body is at rest or in motion
Statics
• Study of the force components on a particle that is in equilibrium
(either at rest or moving uniformly in a straight line)
Dynamics
Kinematics
Geometry of Motion
• Study of the distance and time of motion of a particle, without
direct regard for the force components (yet)
Kinetics
Forces and Motion
• Study of the motion of, and the force components on, a
particle that is acted upon by non-zero resultant force

Kinematics

System of Particles
Rigid Body
• a point mass or a
material point
• two or more bodies
are represented by
particles and dealt
with together
• distance between
any of its points
remains unchanged
under the action of
forces
• if the dimensions of
a body can be
ignored while
studying its
equilibrium or
motion, it may be
treated as a particle
’
First Law of Motion
(Inertia)
• When a particle is at rest or moving uniformly
in a straight line, then the particle is in
equilibrium.
• ∴ resultant force on the particle is zero.
Σ𝑭 = 0
• If the resultant force on a particle is zero, the particle will
remain at rest or continue to move in a straight line.
• Basis of Statics
Second Law of Motion
(Force)
• When a particle is accelerated, then the resultant
force on it is non-zero and proportional to the
acceleration by a factor equal to the mass.
Σ𝑭 = 𝑚𝒂
Third Law of Motion
(Interaction)
• When two particles interact, then the
action and reaction forces have the same
magnitude, same line of action, and
opposite senses.
Dimensional Homogeneity
• Each term must be expressed in the same unit
Significant Figures
• Determines the accuracy of the number
• For our final answers, we use 4 significant figures if the answer
starts with "1", 3 significant figures otherwise.
Rounding Off Numbers
• Determines accuracy of the result
a chain can never be stronger that its weakest link

Unlike the song Oh Cecilia, I don't break hearts, but I can
shake your confidence <3
• Gew: I hope that amidst the somewhat difficult and
demanding nature of this course, we can all still put a
smile in our faces every once in a while and get a chance
to pause and be proud of ourselves with our efforts (like
celebrate the small wins of accomplishing a
module/assessment even if we found it hard and took a
lot of time in completing). Good luck to us!
