Question B6. Which of the following is not correct? (a) The modulus of timber depends on the density of the timber. (b) Timber is a composite based on cellulose polymers which means that its properties are time dependent and timber will creep with time under load. (c) The toughness of timber is reduced by the presence of knots and defects in the structure. (d) Timber is usually dried before use to reduce its moisture content and reduce warping during use....

10.1. (Multiple choice) Which one of the following statements is true? (a) The corrosion of a metal immersed in acid requires the presence of oxygen. (b) Cathodic protection involves attaching a more cathodic material to a metal that you want to protect from corrosion. If two pieces of clean, unpainted 1040 steel sheet are immersed near to each other (but not touching) in seawater, they will corrode at the same rate. (c) (d) Corrosion always involves the transfer of electrons....

Q-1. You are testing a circular beam of two metals, 1045 steel and 2014-T6 aluminum, in a rotating-cantilever beam fatigue test. If you need to choose one of these metals so that you can essentially design a part made of that metal, and subject the part to a repetitive stress- amplitude without ever failing due to fatigue, which one would you choose (See the attached figure) 600 T-51-25 tanium alloy 500 00 Maximum 8 MP 300 Ductile Castro 200 700...

i
think i understand how to get the molecular equation and also the
net ionic equation maybe, but i dont know how to get the total
ionic equation. thanks so much!
total for each single replacement reaction that did occur. If the metal was not oxidized, indicate that by a molecular equation like Equation (7) in the DISCUSSION section and skip writing the ionic equations 1.
