A glass bottle of sparkling water has a cap made from high density polyethylene with a thickness of 1.2 mm and diameter of 26 mm. If the carbonation pressure is 300 kPa, estimate the deflection at the centre of the cap after 3 months. (8) A piece of thin wall polypropylene (diameter of 254mm) is rotated about its longitudinal axis at a speed of 2500 RPM. How long does it take for the diameter of the pipe to increase by 1mm, and how long does for an increase of 2mm? Density of the material is 900 kg/cubic metre. (6)
