9 new video tutorials and 9 fully solved practice problems have been added to the Engineering Dynamics course, completing the Work & Energy chapter! They cover the basic variables and equations that you’ll need to solve Work & Energy problems. Some of the topics covered are conservative and non-conservative forces, the conservation of mechanical energy, the principle of work and energy, mechanical power, and mechanical efficiency. |

Have you ever wondered why Engineer4Free exists, and who is behind it? Listen to Episode 30 of the Civil Engineering Academy Podcast, where I share some details about why I started Engineer4Free and where it’s going in the future. The Civil Engineering Academy is an excellent resource for those looking to pass the FE and PE exams. They do a great Podcast on all things Civil Engineering, as well as practice exams, review courses, and even Professional Development Hours (PDH) that you can put towards the continuing education requirements to maintain your PE licence.
