Early engineering works (1900s) assumed that rock was infinitely strong (T/F) - answer-True What is the name of the phenomenon, typical of very deep mining, that describes rock effectively "imploding" in the excavation? - answer-Rockburst Photo-elasticity was used in the early days of rock engineering to look at how stresses were redistributed around an excavation. In terms of mechanical behaviour of rock masses, what was the underlying assumption of that technique. - answer-Rock masses ...

Geography (AQA GCSE) Latest Update Already Passed How are waves formed The wind blowing over the sea, friction with the surface of the water causes ripples to form and these develop into waves Constructive waves Low waves that surge up the beach, powerful swash weak backwash, deposit large amounts of material, crests far apart, gently sloping wave front Destructive waves Formed by local storms near the coast, powerful backwash, closely spaced, high and steep, weak swash, narrow the beach, stee...
