The code would make a lot more sense with some basic objects to represent a force, bolt, and bolt pattern. However, this implementation would be a major code refactoring and testing. I want to make note of it and implement it in the future.

The following is generally what I think the classes will look like but this is certainly subject to change.

Bolt

Data Members

• bolt number
• user_x
• user_y
• (user_x, user_y)
• cx
• cy
• [cx, cy]
• Rsx
• Rsy
• [Rsx, Rsy]
• Rex
• Rey
• [Rex, Rey]
• R
• dx
• dy
• [dx, dy]
• d
• delta
• r (ratio of R/Rult)
• Rux
• Ruy
• [Rux, Ruy]

Methods

• calculate d
• calculate delta
• calculate R
• calc_bolt_coords_wrt_centroid; return cx, cy
• update_bolt_coords_wrt_ic; returns dx, dy

Bolt Pattern

Data Members

• ixx
• iyy
• j
• dmax
• rult
• x_cent
• y_cent

Methods

• calc_ixx
• calc_iyy
• calc_j
• calc_centroid
• find_dmax

Force

Data Members

• user_x
• user_y
• user_z
• (user_x, user_y, user_z)
• px
• py
• pz
• (px, py, pz)
• mx
• my
• mz
• [mx, my, mz]
• cx
• cy
• cz
• [cx, cy, cz]
• e
• rx
• ry
• [rx, ry]

Methods

• calc_force_coords_wrt_centroid; return cx, cy, e
• calc_moments_about_centroid; returns mx, my, mz
• update_force_coords_wrt_ic; returns rx, ry
