Unlike the tensile effort, which tends to straighten the parts, the compression effort tends to accentuate the effect of the initial curvature. The lateral displacements produced make up the flexural buckling process. The buckling of the part tends to reduce its load capacity.

Checking the safety of compressed parts varies depending on the slenderness of the part. A column with a circular section and buckling length equal to 320 cm is classified as moderately slender. Knowing that it receives a centered force of 480kN, carry out the necessary calculations and select the alternative that presents the requirements associated with its correct dimensioning.
Alternatives
Alternative 1:
A simple compression generated by the load 480.0 kN.
Alternative 2:
A simple compression generated by the load 512.0 kN.
Alternative 3:
A flexion-compression caused by a load of 480.0 kN plus a moment of 5.1 kN.m.
Alternative 4:
A flexion-compression caused by a load of 480.0 kN plus a moment of 24.0 kN.m.
Alternative 5:
A flexion-compression caused by a load of 480.0 kN plus a moment of 512.0 kN.m.

- You have been asked to draw up a specification for a ceramic cladding tile that is likely to experience tensile stresses of 64 MPa during its installation and service lifetime. If the ceramic has a specific surface energy of 0.28 J/m2 and its Youngs Modulus is 82 GPa what would be the maximum length of an internal flaw that would not result in fracture of the tile?

- I need the answer as soon as possiblearrow_forwardTopic: Thermal & Torsional Stress The rigid, horizontal slab is attached to two identical copper rods. There is a gap ∆ = 0.18 mm between the middle bar, which is made of aluminum, and the slab. Neglecting the mass of the slab, calculate the stress in each rod when the temperature in the assembly is increased by 60 o Use the following data:arrow_forwardIn an engineering application, the material is a strip of iron with a fixed crystallographic structure subject to a tensile load during operation. The part failed (yielded) during operation and needs to be replaced with a component with better properties. You are told that two other iron strips had failed at yield stresses of 110 and 120 MPa, with grain sizes of 30 microns and 25 microns respectively. The current strip has a grain size of 20 microns. The diameter of the rod is 1 mm and the load applied is 100 N. What is the yield stress of the new part C and would you recommend it for operation? Select one: a. O b. 129.5, yes C. 133.5 MPa, yes e. 120.5 MPa, no d. 140.5, no 123.5 MPa, yesarrow_forward
