The member shown below is fixed at O and its dimensions are h1 = 1.10 m, h2 = 0.20 m, and w = 0.50 m. A force F of magnitude F=51 N is applied at point A. (Figure 2)What is the magnitude of the moment of the force about point O?

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

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.
