A 0 Q3 A steel plate with a square hole in the middle of the plate is subjected to a uniform distributed tensile stress of 1PQR N/m as shown in Figure Q3.1 The modulus elasticity of the plate is 210 GPa with Poisson's ratio 0.25. The thickness of the plate is 5 mm. Due to the symmetrical shape, consider only the first quarter of the model as in Figure Q3.2. Use this boundary condition: All nodes in line AB must be restrained in vertical direction (y axis) and all nodes in line CD must be restrained in horizontal direction (x axis). PQR is the last three digits of your student matric number. 1PQR N/m 100 mm 100 mm 600 mm Figure Q3.1 A steel plate with a square hole 1 F 2 F2 3 F3 4 FA 5 FS B Figure Q3.2 One-quarter model of the entire problem 500 mm
