As a result of the course a student is able to:
- Make a Free Body Diagram of a two dimensional structure
- Calculate the forces and moments on a structure
- Formulate the equations of equilibrium on a static structure in a two dimensional space, based on a Free Body Diagram
- Recognise different states of equilibrium and determine whether a construction is statically determined, under determined or overdetermined
- Calculate the centre of gravity of a two dimensional body
- Determine the forces in the presence of friction
- Determine the internal forces in a basic, slender beam, on which distributed forces, point forces and/or moments are acting
This is a part of module 1, ME 1 Design and Manufacturing of the Bachelor Mechanical Engineering. See here for the compete description of the module.|
Forces are an essential element of designing a product. The product is loaded by or transfers forces. A product will fail or deform too much if the forces acting on the product are too large. A Free Body Diagram is an essential tool to understand which forces act on the product. This concept is explained in the lectures. The magnitude of the forces, moments and couples are determined using the Free Body Diagram and Newton's Laws.
The second topic in the course is the location of the centre of gravity. This virtual point in the product determines whether the product stand stable on its foundation or support.
The third topic in the course is friction. Friction relates the forces in the contact surface to the normal forces acting on the structure. Friction forces are forces that need to be overcome but, alternatively they can be used to fix the position.
After investigation of all external forces, the basic internal forces are addressed. This implies the normal and shear forces and bending moment in slender beams. These forces will be transformed to stresses and deformations in the course Mechanics of Materials (module 4).
Non-ME students can take this course if they meet the entry requirements.
