26. A slab is subjected to two independently and normally distributed forces F₁ ~ N(500,5²) N and F₂ ~ N(250, 2²) N. If the mass of the slab is m ~ N(100, 2.5²) kg, determine the x, y, z components of the reaction at A where the slab is fixed to the box. Assuming the thickness of the slab is negligible.
