Chapter 11:Kinematics of paricles

Dynamics: Deals with objects moving with an accelerated motion.
It's concerned with the equilibrium of these objects.

Kinematics: It relates position, displacement, velocity, acceleration, and time.

Rectilinear motion of particles.
A particle is in rectilinear if it is moving along a straight line.
*Position: Xp: position coordinate of the particle
: algebraic scalar
rp: position vector
*Displacement:

Bridge Collapse

Just like the World Trade Center collapse the Minneapolis bridge collapse was probably do to a fatigue in the steel pins.

The National Transportation Safety Board(NTSB) will use a special software developed by a local university to analyze the collapse. This is why learning programming is important. A individual invented the software that will analyze the disaster.

I will start to update this blog with the tools I need to continue in engineering.
