Some functions I use to plot beams, supports and loads for strenght of materials courses.

I haven't write proper docs, but please see the examples in the notebook, I think that they are self explanatory.

Available functions are:

showsave(name)

Prints and saves images given a name.

rotate(vx, vy, angle)

Helper function to rotate arrays.

rep_vector(x1, y1, x2, y2, lineformat='-', label='', shw_label=True, shw_mag=False, shw_angle=False, shw_legend=True, aligned=False, arrow_scale = 0.02, offset = 1, fdict={})

Plot a vector (line with arrow). It can show a legend and magnitude and angle values.

rep_pinned(x, y, scale=1, label='', shw_label=False, rotation=0, lineformat='k-')

Plot a pinned support.

rep_roller(x, y, scale=1, label='', shw_label=False, rotation=0, lineformat='k-')

Plot a roller support.

rep_fix(x, y, scale=1, label='', shw_label=False, rotation=0, lineformat='k-')

Plot a fixed support.

rep_none(x, y, scale=1, label='', shw_label=False, rotation=0, lineformat='k-')

Plot a beam end without suppport, helper function to place labels.

rep_axis(x=0, y=0, scale=1, shw_label=True, lineformat='k-')

Plots x,y axis lines.

rep_element(x1, x2, y1, y2, lineformat='k-', fill=True)

Plots a beam or element (filled rectangle).

rep_leng(x1, x2, y1, y2, lineformat='k-', offset=-1, label='', shw_label=True, label_offset=0.5, arrow_scale=0.015)

Plots a aligned lenght measure.

rep_dist(x1, x2, y1, y2, lineformat='k-', arrows=3, function=(lambda x: 1), offset=-1, label='', shw_label=True, label_offset=0.5, arrow_scale=0.15)

Plots a distributed load.

rep_pair(x, y, diameter, start_angle, end_angle, lineformat='k-', label_angle=0, offset=-1, label='', shw_label=True, label_offset=0.5, arrow_scale=.6) '''Plots a couple force (moment).'''
