A rectangular plate L = 0.1 m long and W = 0.2 m wide (into the page) is oriented at an angle of attack α = 18° with respect to air moving at U[infinity] = 8 m/s . The circulation around a cross-section of the plate is measured to be Γ = 100 m^2/s. Required:a. Is the flow laminar or turbulent?b. Determine the lift coefficient CL. c. Determine the drag coefficient Cp.

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.

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives
