A strain guage consists of a wire of total length 3m
and resistance 750 Ohm. A force causes the longth of the
wire to increase to 3.005 m. Calculate the change in
resistance of the guage ?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?
