Three identical circular disks A, B and C are welded to the ends of three identical solid circular bars (see the figure). The bars lie in a common plane and the disks lie in planes perpendicular to the axes of the bars. The bars are welded at their intersection D to form a rigid connection. Each bar has diameter di = 0.4 in. and each disk has diameter d2 = 4 in. 135 135 90° Forces P, P2, and P3 act on disks A, B, and C, respectively, thus subjecting the bars to torsion. If P = 30 lb, what is the maximum shear stress Tmax in any of the three bars? Round your answer to the nearest ten. Tmax psi

Temperature related material properties

Temperature-related properties of materials are the properties that change or show any variation with temperature variations. Various properties of materials include physical properties, mechanical properties, chemical properties, electrical properties, magnetic properties, etc. The chemical, electrical, and magnetic properties of materials are important, but the physical and mechanical properties are more important. Based on their composition and chemical bonding, materials are classified as metals, ceramics, polymers, and composites.
