Question 1 5 pts Select all the correct answers from the list below. If a statement includes a fact and a reason, both must be correct for the statement to be correct. There is an unspecified number (N) of correct answers. For each correct answer, you will receive 5/N marks, but you will lose 5/N marks for any incorrect answer selected. Your total mark will not go negative. Crazes tend to form along the maximum shear stress and can carry some load. The Boltzmann Superposition Theory can only predict creep behaviour, not recovery An ideal rubber is stiffer in tension than in compression The Boltzmann Superposition Principle is limited to linear viscoelastic behaviour Miner's rule only works if the failure mechanism does not change. With rubbers, the stiffness can be charged easily by changing the cross-link density
