Overview:: This video takes a detailed look at lift, starting with how it is linked with the pressure distribution around airfoils. We also cover a few different explanations of lift, including the Bernoulli Principle and Newton's Third Law explanations. Circulation is a key aspect of lift that it is important to grasp to develop a more complete understanding of lift so that's covered too, as is the Kutta condition. Finally we explore how the lift force varies with the angle of attack of the airfoil (which explains why aerobatic aircraft use symmetrical airfoils), and how stalling can result in a dangerous loss of lift.
Type of Material:: Animation (video)
Recommended Uses:: It could be recommended for courses on mechanical properties of materials in fluid mechanics engineering topics. Useful for traditional and hybrid/blended teaching
Technical Requirements:: Mozilla Firefox, Google Chrome and Microsoft Edge browsers were used to access the material. It seems that all facilities are active for any browser.
Identify Major Learning Goals:: The video is addressed to students of mechanical and aeronautical engineering degrees interested in learning about fluid mechanics.
Target Student Population:: Grade School, Middle School, High School, College General Ed, College Lower Division, College Upper Division, Graduate School, Professional

Rating:
Strengths:: The video presents lift phenomena in relation with airfoils. It essentially describes the relationship between the pressure, velocity, and lift of a flowing fluid around an airfoil. This video shows how several approaches can be used to explain lift, and it explores a range of different applications. Contents are presented in a clear and concise manner. The contents are core concepts in basic fluid mechanics in engineering courses. Information is provided accurately and summarizes well the main ideas.
Concerns:: No concerns

Rating:
Strengths:: The material could be used for self-learning as well as a supplementary material in traditional or blended/hybrid courses on fluid mechanics. The learning objectives are clearly stated. Physical phenomena and examples concerning the application of Bernoulli's equation and Newton’s Third Law are presented graphically, easy to understand.
Concerns:: As corresponds to video materials, to become useful for effective learning it should be combined with extra exercises and quizzes, or to become integral part of additional lectures on the topic of fluid mechanics.

Rating:
Strengths:: This website offers to design educational videos to better help students and professionals in general on the different topics of engineering technologies. The audiovisual content of these videos supports, helps and boosts the effectiveness of learning.
Concerns:: As corresponds to video materials, limited interactivity.

Other Issues and Comments:: In recent years, video has become part of education as a learning and communication medium to transfer knowledge, visualize a process or even analyze a situation. Its use continues to increase in pedagogies. Today, digital, more particularly, video, is used to provide online training, hybrid training and flipped classroom. The use of these videos, as a complementary tool, improves some of the initial topics in the fields of engineering technologies.
