Acompound die is used to blank and punch a large washer out of 6061st aluminum alloy sheet stock 3.2 mm thick. the outside diameter of the washer is 25.0 mm, and the inside diameter is 12.0 mm. determine the punch and die sizes for (a) the blanking operation, and (b) the punching operation.

Which best describes the difference between internal and thermal energy?

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
