Concept explainers
Resistors in parallel Two resistors wired in parallel in an electrical circuit give an effective resistance of
a. Graph the resistance function using the window [0, 10] × [0, 10] × [0, 5].
b. Estimate the maximum value of R, for 0 < x ≤ 10 and 0 < y ≤ 10.
c. Explain what it means to say that the resistance function is symmetric in x and y.

- Write a CNC G-code program to machine the part in the following figure, so that the tip of the tool follows this path: rapid movement to a point above P8, with z=4 . using absolute dimensioning change to tool "4, with a clockwise spindle speed of 2500 rpm, with coolant on and a feed rate of 14 in./min using incremental dimensioning -rapid movement to 4 in. above P1 -rapid movement to lower the tool to be 0.1 in. above the top surface of the part -move the tool to be 0.5 in. below the top at a 14 in./min feed rate -follow the path around the perimeter to points P2 through PI, ending at P1, using the 14in„/min feed rate turn off the spindle and coolant use absolute dimensioning to return to the start point end the programarrow_forwardHow are the absolute maximum and minimum similar to and different from the local extrema?arrow_forward
