Athree-point bending test is performed on a spinel (mgal2o4) specimen having a rectangular cross section of height d = 3.8 mm and width b = 9 mm; the distance between support points is 25 mm.

(a) compute the flexural strength if the load at fracture is 350 n.
(b)the point of maximum deflection δy occurs at the center of the specimen and is described by

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.
