Hydrostatics: Newton's 2nd Law and Moments

This lecture covers the principles of hydrostatics, focusing on Newton's 2nd law for unit volume and the calculation of moments around the origin. The instructor explains the concept of hydrostatic forces on submerged surfaces, emphasizing the application of pressure and centroid. The lecture also delves into the calculation of torque and moments, providing insights into the mathematical derivations and practical applications. Additionally, the lecture discusses the forces on curved submerged surfaces and the vertical projection of forces. The content is illustrated with examples and equations to enhance understanding.
