A three-point bending test was performed on an Al2O3 specimen having a circular cross section of radius 5.0 mm. The specimen fractured at a load of 3000 N when the distance between the support points was 40 mm. Another test is to be performed on a specimen of this same material, but one that has a square cross section of 15 mm length on each edge. At what load would you expect this specimen to fracture if the support point separation is maintained at 40 mm?

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.
