For a table shown in Figure 1 calculate Poisson's ratio if four legs of the table in the form of solid cylinders are to support a total load of 4000 kN with a safety factor of 2. Diameter, D, of the redesigned leg is 160 mm. Diameter of the leg will increase by 0. 062 mm, The length of the table leg is 1.4 m and the decrease of the leg length due to the load must not exceed 1.8 mm. Express your answer to one significant figure. Do not include the units in your answer. FIGURE 1: IKEA TABLE
