lezione3 Question Title * 1. which one of the following statement is true in a rubber compound applied stress and deformation are in phase in a rubber compound applied stress and deformation are cyclic in a rubber compound applied stress and deformation are out of phase in a rubber compound there is a delay between the applied stress and deformation observed. Question Title * 2. Which is the main effect of the compound hysteresis? the reduction of the modulus the heat generation due to the friction rubber specimen heating phenomenon when it is repeatedly stretched and released Question Title * 3. which rubber good is working in constant strain condition a tyre a shock absorber a rubber spring a rubber conveyor Question Title * 4. What is payne effect a physical law which describe the rubber behavoiur during deformation a phenomenological explanation of the contribution of the rubber crossling rubber to the modulus An explanation of the rubber stress softening by a phenomenological model Question Title * 5. which is the tipical frequency of tyre "free" rolling depend on tyre diameter depend on temperature depend on speed depend on tyre diameter and speed Other (please specify) Question Title * 6. what does rolling resistance mean is the energy that is lost when the tire is rolling is the energy absorbed when the tire is rolling is the tyre specific rolling distance dissipated energy is the stored energy due to the friction while tire is rolling Question Title * 7.
