As a graduate site engineer, you have been asked to check the formwork design for a 2400 mm high concrete wall to be poured at a rate of 25 mm/min. The design pressure on the plywood is 50 kN/m. Sheathing will be 1200 x 2400 mm sheets of 18 mm thick plyform. The plyform has a specified allowable flexural and shear stresses of 10.0 N/mm2 and 1.50 N/mm, respectively. Moreover, its specified elastic modulus value is 7.0 kN/mm. The designers have spaced the plywood supports at 0.3 m. What will be the expected plywood deflection in millimeters (mm) with this design?
