The radius of the tube is 1.3 mm. The surface tension of water at 20°C is equal to 0.0728 N/m. The water-glass interface is 73°. Compute the capillary rise.

A solid aluminum [E = 70 GPa; a = 22.5 x 10-6/°C] rod (1) is connected to a solid bronze [E = 100 GPa; a = 16.9 x 10-6/°C] rod (2)vat flange B as shown. Aluminum rod (1) has an outside diameter of 42 mm, and bronze rod (2) has an outside diameter of 128 mm. The bars are unstressed when the structure is assembled at 30°C. After the 300-kN load is applied to flange B, the temperature increases to 45°C. Determine the normal force in rod (1).
