A truss-type structure is constructed of four equal bars of 1.23 meters long (AC, CD, AB and BD) and one bar of 0.78 meters (BC). All bars are of square section of 0.9 in, have a modulus of elasticity of 29,000 ksi and the BC bar has in its center a sensor that measures normal unit deformation. All connections on the bars are pins. If the sensor measures a normal unit shrinkage of 0.00008; What is the magnitude of the F-force in kips?
A structural component in the form of a wide plate is to be fabricated from a steel alloy that has a plane strain fracture toughness of 88 MPam (ksi √/in.)) and a yield strength of 880 MPa (63820 psi).
