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).
A combined load comprises a radial and an axial load acting simultaneously. The ability of a bearing to carry an axial load is determined by the angle of contact a-the greater the angle, the more suitable the bearing for axial loads. An indication of this is given by the calculation factor Y, which becomes smaller as the contact angle Î± increases.
