and direction The net force acting on a body is the sum of all forces acting on it When the net force is zero the body is in equilibrium remaining stationary or moving at a constant velocity This principle of equilibrium is crucial for analyzing structures ensuring they remain stable and withstand applied loads 2 Moments and Rotational Equilibrium Moments also known as torques represent the tendency of a force to cause rotation around a specific point The magnitude of a moment is the product of the force and the perpendicular distance from the point of rotation Rotational equilibrium is achieved when the sum of all moments acting on a body is zero preventing the body from rotating 3 Stress and Strain The Response of Materials When a force is applied to a material it experiences stress which is the internal resistance to deformation The force per unit area represents the stress Strain on the other hand measures the deformation of the material under stress The relationship between stress and strain is known as the materials constitutive law which describes how the material behaves under loading conditions 4 Material Properties Elastic and Plastic Behavior Materials
