14. A solid steel shaft of 0.2 m diameter has a bronze bush of 0.3 m outer diameter shrunk on to it. In order to remove the bush, the whole assembly is raised in temperature uniformly. After a rise of 100°C the bush can just be moved along the shaft. Neglecting any effect of temperature in the axial direction, calculate the original interface pressure between the bush and the shaft. For steel: E=208 GN/m², v=0.29, a = 12 x 10-6 For bronze: E= 112 GN/m², v=0.33, a= 18 × 10 per per

14. A solid steel shaft of 0.2 m diameter has a bronze bush of 0.3 m outer diameter
shrunk on to it. In order to remove the bush, the whole assembly is raised in
temperature uniformly. After a rise of 100°C the bush can just be moved along the
shaft. Neglecting any effect of temperature in the axial direction, calculate the
original interface pressure between the bush and the shaft.
For steel: E = 208 GN/m², v= 0.29,
a = 12 x 10-6 per
a = 18 × 10 6 per
For bronze: E= 112 GN/m²,
v=0.33,
