Dynamics

Goals

1. Describe dynamics.
2. Excel at applying dynamics in the real world.
3. Effectively solve > 80% of typical dynamics textbook problems.

What?

Dynamics is the branch of physics that involves loads and motion when objects are accelerating.

Commonly, Dynamics is taught as a course to engineering students.

Why Learn (WIFM)

WIFM stands for “what’s in it for me.” Here are some reasons why learning dynamics is worthwhile.

1. Dynamics equips you in part to analyze and design systems that involve motion: Motors, ships, manufacturing plants, mechanisms of all kinds, robots, automobiles, computer keyboards, chain saws, motorcycles, bridges and buildings because they move under the action of loads, the human body as in running.

2. Learning dynamics equips for success in more advanced subjects.

3. Many of us find dynamics inherently interesting and sometimes highly non-intuitive. Thank goodness that brilliant people have figured this subject out for us.

4. You’ll gain a view of the world with respect to motion that is far richer.

How to Excel at Dynamics

First, figure out a few core fundamentals like force, acceleration, torque, angular velocity, and Newton’s law of motion.

Second, systematically apply them to every relevant problem you encounter.
