As an engineering student, subjects like Physics, Calculus, and Chemistry are some of the important subjects in this course. But not all students can immediately understand what the professor teaches in only one sitting. This video gives a great introduction to static equilibrium as this topic is very important for engineers. It is essential since it is the engineer's responsibility to develop and construct a structure that is stable and does not fall, slide, or tilt. Static equilibrium is not an easy lesson and there are many formulas that need to be remembered but the lecturer of this KZbin channel gave an easy-to-understand explanation of the topic so that students could understand it right away. He also gave real-world practice problems to further deepen the students' understanding of static equilibrium. Furthermore, the ability to rewind a tutorial video on social media will be very helpful to learners if they are having trouble understanding a part of the lesson they are studying. The video is a guide for students to clearly understand those complicated topics. However, it is crucial that students have their notes from discussions with their professors that could be a big additional help upon reviewing the topics that had been tackled. #Surviving #TheFutureEngineers #NextGenerationEngineers

At 55:15, is the angle measure between the forces really supposed to be different to the angle measure between the ladder and the ground? Because if you take the length of the ladder (hyp = 10) and the height (opp = 8), then you'd get theta=arcsin(8/10)=53.13deg
