Internal forces are the resisting actions that develop within a solid to balance the effect of external loads. Their measure is expressed as stress, which represents the internal force per unit area acting across imagined sections within the material.
Lessons
Mathematics forms the backbone of understanding solids and structural engineering. Key topics include algebra, calculus, and differential equations, which help analyze stress, strain, and deformation in materials. Vector and matrix operations are crucial for solving problems in structural mechanics, while linear algebra assists in studying stability and equilibrium.
