179167DE MECHAN.
De uer a cauſa .30. quæstionis.
CAP. XXIIII.
VEra ratio, cur homo dum ſedet ( non tamen Turcarum more ) ſi velit
ſeſe in pedes erigere, calcaneos retrahit, vt efficiat angulum acutum, cum fae-
moribus
coxis à parte inferiori, & ventrem inclinat, ad conſtituendum etiam angu
lum acutum in ſuperiori parte, ea eſt;
vt totius corporis pondus, ex ęquo, ideſt ab
oppoſitis partibus circundet lineam rectam, quæ tranſit per locum, in quo conquie
ſcunt pedes verſus mundi centrum.
ideſt, ut edatur ęquilibrium ponderis ipſius cor-
poris circum lineam illam, quę ſub pedibus inſeruit pro ſparto.
Vnde aperiendo,
deinde dictos duos angulos circa dictam lineam, abſque vlla difficultate erigitur cor-
pus, & abſque periculo in alterutram partem cadendi.
Deratione .35. & ultimæ quæstionis.
CAP. XXV.
VEra ratio, quare, quę reperiuntur in vorticibus aquarum, ſemper verſus
medium ipſarum vertiginum vniuntur, inde promanat, quod media
vertiginum ſemper depreſſiora ſunt.
vnde quòd dicta corpora ad medium acce-
dant, nihil aliud eſt, quàm ipſa corpora ſuo pondere grauitateq́ue deſcendere, figu
ra enim vorticibus eſt quaſi conica, & concaua cum angulo deorſum, & gyro baſis
ſurſum.
Atque hæc vera eſt huius effectus cauſa, & non ea quam Ariſtoteles ponit,
à quo aliarum omnium quæſtionum, quas ego omiſi rationes ſunt benè propoſitæ.
