4.6. consider the standard equilibrium heat equation for the temperature of a bar with no source ut = 0 = uxx on x 2 [0; 1]. at x = 0 the flux into the bar fixed f(0) = a, and the x = 1 boundary condition is mixed ktu(l) = kcu0(l). assume kc = 1. show all of your work to calculate the following. (a) solve for the particular solution. (b) using the above, determine the maximum temperature of the bar and describe its relationship to a and kt . (c) determine f(l) a determine dependence on a and kt . (d) explain in physical terms what happens to the boundary flux if limkt! 0+ u(x) =? , and limkt! ¥ u(x) =?

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.

answer:

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.

answer:

design model: consists of design geometry; can be 2d or 3d; typically has a black background.

design files: drawing created with microsoft expression design, a drawing and design program for windows; may contain both vector and raster graphics; can also include multiple layers and various image effects.

elements: an element is a single part of a larger group.
