The major difference between solid and fluid is the molecules are well-packed in solid but free to move in fluid. As a consequence of such difference, which of the following statements are correct? (i) Stress is proportional to strain in solid but stress is proportional to rate of strain in fluid. (ii) Fluid can be used as a lubricating film to separate 2 solid surfaces from direct contact to reduce friction. (iii) The energy required to move a ship slowly is low but increases rapidly with speed. (A) (B) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above

If the viscosity of SCl2 gaseous molecule at 20.0 °C and 1 atm. is 132 pP. what is the viscosity of 7cz gaseous molecule in pP at the same temperature and pressure assuming both molecules having the same cross section? (MM of 35c - 35.0g mol MM of 37a - 37.0 g mol1)
What kinds of properties might you expect molecular mechanics to be unable to calculate?
Explain why the viscosity of a liquid decreases with temperature—that is, how might increased temperature reduce the effects of cohesive forces in a liquid? Also explain why the viscosity of a gas increases with temperature—that is, how does increased gas temperature create more collisions between atoms and molecules?
1. Consider a situation where two volumes of water, one hot, one cold, are both added to a foam cup. (a) Sketch a diagram for the cup and volumes of water, using a dashed line to separate the two volumes, and label all the components. (b) To your sketch, add a line and label it to indicate the heat flow in this system. For now, asssume the foam is a perfect insulator. (c) Write the mathematical relationship between the heat flows for the hot and cold water, hot and cold based on you diagram from parts (a) and (b). (d) Once the water is well-mixed, both volumes of water come to the same temperature Tf. Write the mathematical expressions for the temperature changes for each of the volumes of water, ATcold and AThot, assuming they started at Tcold and Thot for the cold and hot water respectively. (e) Assuming that the foam undergoes the same temperature change as the cold water (it's no longer a perfect insulator!), write a modified version of your equation from part (c) that relates the…

In the appendices, the modulus of elasticity for silicon nitride is 304 GPa (that of steel is 207 GPa). How much porosity could be present in the round bar of silicon nitride such that it equals the reported value for steel?
(6) There are many kinds of polyethylene foam, each with different properties. The low density polyethylene foams (as seen in this video) are very flexible. Remember: in solid mechanics, "flexible" just means that in comparison to other materials, the material deforms quite a bit, relative to the stress. For torsion, the material property that relates to stiffness is the shear modulus (or modulus of rigidity), G. We'll say that G = 6 MPa. a) Complete the FBD. b) Compute the shear stress at Point B. c) Illustrate it on a stress element. d) Report the shear strain at B (in radians). e) Compute the rotation of the top plane. f) Compute arc length s.
