The spindle of a high precision machine is subjected to 200 kgf overhang load at 60 mm from the nearest bearing. It is subjected to 50 kgf load at mid span, between the anti-friction bearings. Find the spindle diameters in the overhung portion to optimize the span length. The spindle is transmitting 5 kw at 110 rpm.

Solutions

Expert Solution

Solution:- The overhung portion diameter of the spindle has been calculated on the basis of combined bending moment and torsional moment. The material of the spindle has been assumed to be C45/55 and loading on the spindle has been assumed to be fluctuating with light bending moment.

. A rectangular steel bar is subjected to a fluctuating load from 30 kN tension to 30 kN compression. The bar is 30 mm wide and 7 mm thick with a hole in the middle that is 4 mm in diameter. Find the fatigue and yield factor of safety if the steel is cold-drawn AISI 1040. If the fatigue factor nf<1 and ny>1 then that means that the system will fail at a finite number of cycles. If that is...
