Answer:
The force needed to cut the sheet metal is 171 kN.
Explanation:
Force (F) needed to cut the sheet metal is the ultimate tensile strength of the material multiplied by the area of the rectangle.
ultimate tensile strength = 190 MPa = 1.9×10^8 Pa
area of rectangle = (15/1000) × (60/1000) = 0.015×0.06 = 0.0009 m^2
F = 1.9×10^8 × 0.0009 = 171,000 N = 171,000/1000 = 171 kN
No I don’t sorry, I hope you do well
Complete question is;

Explanation:
Answer: b) False
Explanation:Ceramic is brittle in nature therefore it has a tendency that it is strong during the compression and it tends to be weak during the high tensile forces. While the tensile forces are applied , ceramics are not able to yield the stress and cause breakage of the material due to high tension but does not face any fault during the compression.
