Standards suggest that reflectance value for walls should be 50-70%, floor 20 40% and for ceiling 60 80%. Therefore by checking up on against these recommendations, 27 cases are shortlisted. Out of these, finally 9 cases are selected. The 27 cases are reduced to 9 cases.
Axial Stress. Fig. Axial Stress (aka compressive stress, tensile stress) is a measure of the axial force acting on a beam quantitatively measuring the internal forces acting within in the beam. Compressive stress means the member is in compression (being smashed) vs. tensile stress which means the beam is in tension (being pulled apart).
STRESS: The force applied to a plane divided by the area of the plane. COMPRESSIVE STRESS: The stress generated by forces directed toward one another on opposite sides of a real or imaginary plane. TENSILE STRESS: The stress generated by forces directed away from one another on opposite sides of a real or imaginary plane. SHEAR STRESS: Stress (force per unit area) that acts parallel to a (fault) plane and tends to cause the rocks on either side of the plane to slide by one another. STRAIN: The result of stress applied to a body, causing the deformation of its shape and/or a change of volume. ELASTIC RESPONSE: The deformation of a body in proportion to the applied stress and its recovery once the stress is removed. ELASTIC LIMIT: The maximum amount of stress a material can withstand before it deforms permanently. DUCTILE RESPONSE: The permanent deformation, without fracture in the shape of a solid.
