The advantages of using light-gauge steel framing members in lieu of wood framing members include all of the following except: a. framing members are significantly lighter than the wood members to which they are structurally equivalent. b. they can be used in buildings for which non combustible construction is required by building codes. c. they provide better thermal insulation than do wood members of the same size. d. steel members tend to be straighter and more uniform than their wood counterparts. e. all of the above.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
