A 220 N block is at rest on a flat, frictionless surface. A cable hooked to the object applies an upward force of 110 N on the object. What is the normal force from the surface acting on the object?

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
