just wrote down what you learned in the class, and show how much you have understood. Or if you could not understand some parts, ask in the lecture-notes, and show where and why you do not understood.

I know Sigma F is the sum of the forces but does sigma Fi mean sum of all Forces in the horizontal direction. I do not feel you explained this very clearly.

Henry Tan's picture

Sigma F is the summation of forces. Notice that forces are vectors. Therefore, Sigma Fi = 0 can be applied to any direction.

Come to my office if still confused.
