Ashaft of solid circular section has a diameter of 30 mm. the allowable shear stress in the material is 50 mpa. determine the power that can be transmitted at 2000 rpm through the shaft.

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

Oxygen at 300 kpa and 400 k is in a closed system with an initial volume of 0.1 m3. is now compressed in a polytropic process, with exponent of n 1.2, to a temperature of 500 k. calculate: a) the boundary work done during the compression, in kj b) the heat transfer during the compression, in kj

Aload of 10kn is to be suddenly applied to the free end of a vertical rod of length 500 mm, the upper end being rigidly fixed. 190 mechanical science what should the diameter of the rod be if the maximum stress in the rod is not to exceed 100 mpa? the tensile modulus of the rod is 205 gpa.
