two straight line AI and IB intersect at a point of intersection I , whose chainage is 1872.435m with an angle of intersection of 148°. They are to be joined by a circular curve whose radius is 300m. Calculate the data for setting out the curve if the chainage interval is given as 25m

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
