Blanking Arithmetic: Cut Perimeter and a Supplied Force Model

Blanking Arithmetic: Cut Perimeter and a Supplied Force Model

Original quantitative learning practice in English. All 24 questions are included. Four supplied cases exercise six related calculation targets; they form one topic, not four separate tests. Every question includes the complete initial data. Use the stated model and retain intermediate precision. Choose one answer. Learning target: 20/24, not an official pass mark. This bank covers the calculation topic in its title; it is not a complete professional examination, design approval or operating instruction.

A rectangular outline has sides 100 and 60 mm and also contains 2 separate round holes of diameter 14 mm. All contours are cut in the same idealised stroke through 1.5 mm material. Use π=3.1416 and supplied shear resistance 250 N/mm². Model force=total cut perimeter×thickness×resistance. This is not a press rating, tooling approval or operating instruction. Calculate the outer cut perimeter in mm. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
