Course description
In manufacturing, we have to take responsibility for our production. Therefore, in order to achieve unbreakable and "safe and secure" manufacturing, it is necessary to quantitatively grasp and understand the forces and moments acting on objects. The purpose of this course is to focus on statics. Specifically, students calculate the forces acting on each part of an object from the balance of forces and moments based on Newton's laws, determine the centre of gravity of an object, and calculate the motion of a faltering point (falling motion or parabolic motion) using differentiation and integration.
Purpose of class
The aim of this course is to give students an idea of the forces acting on the various elements of a structure. The specific objectives are as follows
1. to understand the mechanical terms and quantities
2. to acquire the ability to calculate forces and moments, their synthesis and decomposition
3. to acquire the ability to determine the forces and moments acting on a member.
4. to be able to express and evaluate the motion of a material point by means of mathematical expressions.
Goals and objectives
  1. To calculate the decomposition and composition of forces and moments in terms of vectors.
  2. To determine the forces and moments occurring in a component.
  3. To find the figure centre and centre of gravity of an object.
  4. To understand the motion of a quality point and to evaluate it quantitatively.

Evaluation method and criteria
There will be two reports (worth 20 points), a mid-term examination (worth 40 points) and a final examination (worth 40 points), for a total of 100 points. The report will be divided into two parts.
Out of a maximum of 100 points, 60 points will be considered a pass. Students will be able to calculate the basic quantities of forces and moments and understand their meaning. Students should be able to calculate moment of inertia and second moment of section, formulate equations of motion for quality points, evaluate motion, calculate quantities, and explain motion.
