By da Vinci Leonardo; Landrus, Matthew Hayden
Although Leonardo’s immense Crossbow is considered one of his most well-liked drawings, it's been one of many least understood. "Leonardo’s large Crossbow" deals the 1st in-depth account of this drawing’s most probably objective and its hugely resolved layout. This interesting booklet has a wealth of technical information regarding the enormous Crossbow drawing, as it’s an entire research of this undertaking, even though this is often as available to the final viewers up to it's also informative with new discoveries for the professors of engineering, know-how and paintings. The e-book explores the context of Leonardo’s invention with an exam of the broad documentary facts, a quick background of the nice crossbow and ballista, the 1st actual translation of the textual content and the technical standards, and an in depth research of Leonardo’s layout method for the crossbow, from begin to end. Dozens of preparatory drawings, in addition to the new discovery of approximately invisible steel stylus preparatory incisions lower than the ink of the large Crossbow drawing, are facts of Leonardo’s reason to supply engineers and different audience a radical layout of the large desktop. The ebook proposes those new discoveries with the aid of a technique that have been on the center of Leonardo’s operating philosophy: the proportional approach. As confirmed with an research of the enormous Crossbow venture, he used a constant method of 1/3rd proportions during the layout and drawing strategy and hired this sort of proportional method before everything of just about each very important venture. due to this facts of his wisdom of geometry, facts of his reports of impetus and strength, and due to the hugely polished and complicated nature of the enormous Crossbow layout, a later date for the drawing is proposed within the current ebook, associating the drawing along with his drafting functions round 1490-93.

Das Bemessungskonzept "Betriebsfestigkeit" verfolgt das Ziel, Maschinen, Fahrzeuge oder andere Konstruktionen gegen zeitlich veränderliche Betriebslasten unter Berücksichtigung ihrer Umgebungsbedingungen für eine bestimmte Nutzungsdauer zuverlässig bemessen zu können. Ingenieure, Wissenschaftler und Studenten finden in diesem Buch die experimentellen Grundlagen sowie erprobte und neuere Rechenverfahren der Betriebsfestigkeit für eine ingenieurmäßige Anwendung.
Das Werk beschreibt erstmalig in einer geschlossenen shape eine Simulationsmethode zur schnellen Berechnung von Kontakteigenschaften und Reibung zwischen rauen Oberflächen. Im Unterschied zu bestehenden Simulationsverfahren basiert die Methode der Dimensionsreduktion (MDR) auf einer exakten Abbildung verschiedener Klassen von dreidimensionalen Kontaktproblemen auf Kontakte mit eindimensionalen Bettungen.

It is also possible that Leonardo was familiar with Ferrara particularly at the end of the 1470s and early 1480s, while he studied local fortifications, mills, locks and dams, recording his notes on sheets now in the Codex Atlanticus and Manuscript B. 11 As it happens, his designs for flying machines and naval weapons would have been most helpful in defence of Ferrara’s Po Delta in 1483, allowing quick escapes, assaults, and manoeuvrability around the waterways. Leonardo’s written and illustrated proposals to Ludovico were alternatively useful as a means of honouring the Sforzas’ unfinished business of retaking Genoa and Corsica, not to mention the completion of an equestrian statue of Francesco Sforza.
