Write the nested loops to control the number of rows and the number of columns that make up the letter e, as shown below: *** * *** * *** in the loop body, use a nested if statement to decide when to print an asterisk and when to print a space. the output statements have been written, but you must decide when and where to use them.

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.
