Question

please in a clear answer find me those and using the table for (polyprolene):

the yield stress

the ultimate tensile stress(uts)

breaking strain

Dimension of Polymer Samples Sample Name Polyethylene Polypropylene Epoxy Rubber Width(mm) 12 12 12 4 Thickness (mm) 3 3 5 2 Gauge length (mm) 42 42 42 14

Answer 1

Polypropylene (Thermoplastia) UTS 1400 Yield strength (YS) Load (N) (connespond to 0.21 strerin) by drawling partalled line by 0.2.1, offset ALL 0.2-1. L - 42 mm YS 1200 =) AL 42 0.002 => AL=0.084 mm 19 Ays = 1200 Width x thicknen K 0.20%. Machine Extension (mm) Strain = 0.084 mm 1200 12 X 3 33.33 M Per ultimate UTS (Tensile streength) 1400 1400 38.89 MPa Width x Thicknen 12x 3 49 Masimum machine extension 42 X10oY. brange Length Breaking B streamin 11 45.247.
