Şekilde verilen mil Fe50=St50 malzemeden soğuk çekiler imal edildikten sonra ince talaş alınarak işlenmiştir. Mil 7 kN luk bir kuvvet ve 100 Nm lik tork etkisi altındadır (iki kama yuvası arası tork etkisindedir). Şekle ait kesme, eğilme ve burulma diyagramlarını ölçekli olarak çizdikten sonra, mil üzerinde 45mm lik çapın bulunduğu konumda (kama boyu ortasında) sürekli mukavemet diyagramını oluşturunuz, emniyet durumunu belirleyiniz ve sonuçları yorumlayınız?NOT: Seçmeniz gereken değerler varsa kaynak göstererek seçiniz ve problemi ona göre çözünüz.

3. A 20-mm diameter rod made ofa ductile material with a yield strength of 350 MPa is subjected to torque of 100 N.m and a bending moment of 150 N.m. An axial force is then gradually applied. Determine the value of force when the rod begins to yield. Solve the problem two ways using the (a) Tresca theory (Maximum shearing stress theory) and (b) von Mises theory (Maximum distortion energy theory) [12+12 points

A low carbon steel shaft is designed to have a diameter of 30 mm. It is to be subjected to an axial load (P-30 kN), a moment (M-200 N-m), and a torque (T-300 N-m). Assume the yield stress for the steel is (280 MPa), the Poisson's ratio is (v= 0.29), and the safety factor is (1-1). Calculate the margin of safety using the following failure theories. a.) Rankine Criteria (Maximum Principal Stress) b.) Tresca Criteria (Maximum Shear Stress) c.) Saint...
