(a) Computethe flexural strength if the load at fracture is 350 N (80lb).

(b) If you wereto scratch the ceramic material, how could this affect the testresults? At what location on the sample (relative to where thecenter force is applied) would a scratch have the greatestimpact?

Use polar coordinates to find the volume of the solid under the plane z=4x and above the circle x^2 +y^2= 16 in thed xy planeplease show work

A threepoint bending test is performed on a spinel(MgAl₂O₄) ceramic specimen having arectangular cross section of height of 3.8 mm and widthof 9 mm; the distance between supportpoints is 25 mm.
