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?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
