What is the magnitude of the maximum stress that exists at the tip of an internal crack having a radius of curvature of 4.5 × 10-4 mm (1.772 × 10-5 in.) and a crack length of 3.5 × 10-2 mm (1.378 × 10-3 in.) when a tensile stress of 180 mpa (26110 psi) is applied?

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
