Greetings,

m1_cols = h1gamma_UC254 + h2gamma_UC203 #(kg) Mass of half of columns above and below level 1
Why we considered only weight of one column? shouldn’t be 2 x (h1gamma_UC254 + h2gamma_UC203)

Hi, we’re considering half of the height above and below for 2 columns, which is the same as the full height above and below for 1 column - which is what we’ve written in the code - the mass is the same.

Hiya! You could move the calculations for the x, y, and z matrices outside the for loop to avoid recomputing them at every iteration. Also, note that np.matrix has been deprecated in modern NumPy, so it’s better to use np.array instead.
