Outlines  Stress Concept  Types of Stresses  Applications on Stress  Design of Materials Due to Stress Capacities

Stress Concept Stress is the distribution of a force throughout the cross-sectional area of a structural member

Types of Stresses

Applications on Stress

Types of Stresses

Applications on Stress

Design of Materials Due to Stress Capacities

Applications on Stress Ex. 3/ the frame below was supposed by an engineer to support the distributed load (w=20 kN/m) over the carrier which is supported by cable from one side and a platform from the other side, calculate the cable diameter, the carrier height (h) and the required distance from the carrier to be supported by the platform (x) if you know that tension capacity of the cable is (400 MPa.) and the compression and shear resistance of the carrier are (400 MPa.), (200MPa.) respectively.

Applications on Stress
