5. Moments

Moments, also known as torque, are essential in understanding the rotational impact of forces applied away from a pivot point. The concept is fundamental in various fields, especially engineering, where moments ensure balance and influence machine design. The chapter elaborates on the principle of moments, types of moments, and their applications, illustrating how to calculate forces in equilibrium systems and emphasizing the importance of the moment arm in maximizing force efficiency.
