Difference between INTERNAL and EXTERNAL forces

What is internal force and what is external force?
At EngiPRO, we unravel the secrets of structural engineering and reveal how forces define our world. This video introduces you to the fascinating concept of a rigid body, a key piece in structural analysis that does not change its shape or size under the action of external forces. You will learn about the differences between internal and external forces and how the latter can cause changes in the movement or equilibrium of bridges and skyscrapers, from a simple translation to a complex rotation. With clear examples and detailed explanations, we explore the resistance of materials and the design of bridges and skyscrapers, ensuring their structural stability against challenges such as gravity and friction. Subscribe to EngiPRO for more educational insights on the theory of forces and the mechanics of solids in practice!
