This course covers torque, center of mass, rigid bodies in equilibrium, and the stability of objects. The course is a mix of lectures and problem solving tutorials. Students will learn to how to calculate torque, how to evaluate the center of mass of systems of particles and objects with uniform density. I will teach you how to approach problems and help you develop your own problem solving strategies to become a better problem solver. Part 1: Torque What is torque?Understand how torque is different from forcesCalculate torque using 3 different techniques (standard methods, force components, and moment arms)Several example problems to practice Part 2: Center of Mass Learn how to find the center of mass of symmetric objectsCalculating the center of mass of systems of particles in 1D, 2D, and 3D.Practice problems Part 3: Static Equilibrium Conditions for Static EquilibriumProblem solving strategiesPicking the right pivot locationSeveral example problems to practice the problem solving techniques. Part 4: Various Problem Section Practice solving Torque and center of mass problems and compare your answers to those of Physics NinjaSection contains conceptual questions and algebraic questions ranging from easy to very challenging. If at any point you don't understand something in my videos please feel free to reach out. I'm always willing to help someone learn. Physics Ninja always has your back! Happy Learning Dr. E., Physics Ninja and Expert Physics and Math Teacher.
