A horizontal cantilever of uniform section of length l carries two concentrated loads, W at the free end and 2W at a distance ‘a’ from the free end. Starting from the first principles, determine the maximum deflection for the loading.
If the cantilever is made from a steel tube of circular section of 10cm external diameter and 0.6 cm thickness and l = 1.5m, and a = 0.6m, determine the value of W so that the maximum bending stress is 1400kgf/cm2. Calculate the maximum deflection for the loading. Take E=2´106kgf/cm2.
