− | why do things break? to reliably predict what’s going on inside a structure, we need to know the forces that act on it. it’s newton’s law that helps us to determine these forces. basically, this class is all about newton’s law, force equilibrium, and its application to civil, mechanical, aerospace, and biological problems. we explore it for particles first, then for two-dimensional, and finally for three-dimensional systems. first we look at the structure from the outside, then from the inside. we learn how to identify, formulate, and solve engineering problems. to do so, you should be familiar with and not afraid of maths, vectors, and basic physics. | + | why do things break? to reliably predict what’s going on inside a structure, we need to know the forces that act on it. it’s newton’s law that helps us to determine these forces. basically, this class is all about newton’s law, force equilibrium, and its application to civil, mechanical, aerospace, and biological problems. we explore it for particles first, then for two-dimensional, and finally for three-dimensional systems. first we look at the structure from the outside, then from the inside. we learn how to identify, formulate, and solve engineering problems. to do so, you should be familiar with and not afraid of maths, vectors, and basic physics. |

[edit] goals
why do things break? to reliably predict what’s going on inside a structure, we need to know the forces that act on it. it’s newton’s law that helps us to determine these forces. basically, this class is all about newton’s law, force equilibrium, and its application to civil, mechanical, aerospace, and biological problems. we explore it for particles first, then for two-dimensional, and finally for three-dimensional systems. first we look at the structure from the outside, then from the inside. we learn how to identify, formulate, and solve engineering problems. to do so, you should be familiar with and not afraid of maths, vectors, and basic physics.
[edit] grading
- 20 % homework - 5 homework assignments, 4% each
- 25 % midterm 1 - closed book, closed notes, one single page cheat sheet
- 25 % midterm 2 - take home exam
- 25 % final - closed book, closed notes, one single page cheat sheet
the best of the three exams will count 30% towards your final grade
