1. Calculate the Flux Density (B) produced by a 0.02 meter long coil containing 50 tums of wire carrying a current of 0.3 amps. The core is made of Copper with a permeability (u) of 1.256629 x 10 H/m. Permeability of free space is 4TT x 107 (2 Points)

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.

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