You need to be able to calculate thickness of a laminate given the fabric weight and resin content. Current table represents steel equal angles (L profile) sizes, dimensions, properties, specifications. SECTION PAGE I BACKGROUND 1 II TEST PROGRAM AND PROCEDURES 2 1. Rouxel4 In comparing a material’s resistance to distort under mechanical load rather than to alter in volume, Poisson’s ratio offers the fundamental metric by which to compare the performance of any material when strained elastically. Similar to structures under tension or compression, two important mechanical properties of shafts under torque loads are shear stress and shear strain. Plastic Section Modulus Zp is the Plastic Section Modulus Resisting moment Mp = fy x Zp The plastic section modulus assumes the entire section yields. Section modulus = 650 k-ft/ft x 12 in/ft / 31. Use F y = 50 ksi.
