Abstract
Günümüzde tel halatlar, asansör, kren, teleferik ve telesiyej sistemlerinde, maden işletmelerinde, denizcilikte yük kaldırma ve iletme elemanı olarak sıklıkla kullanılırlar. Bu çalışmada, eğilen ve burulan helisel ince çubukların genel teorisi incelenmiş ve bu teori kullanılarak halat demetleri için denge denklemleri oluşturulmuştur. Statik yüklü bir halat demeti için örnek bir uygulama incelenmiştir. Halat demetini oluşturan merkez tel ve dış tellerde oluşan birim şekil değiştirmeler ve gerilmeler hesap edilmiş ve sunulmuştur. Merkez telin toplam yükün %15.58’ini dış tellerin ise %84.42’sini taşıdığı tespit edilmiştir

Abstract
Nowadays, wire ropes are frequently used in elevator, crane, aerial ropeway systems, mine hoisting, offshore systems as materials handling equipment. In this study, general theory of the bending and twisting of thin rod has been investigated and equilibrium equations for rope strands have been constituted by using this theory. A case study of axially loaded rope strand has been investigated. Stresses and strains occurred on center wire and outer wire which form strand have been calculated and presented. It has been determined that center wire carries 15.58% of total load and outer wires carry 84.42% of total load.
