A load resistor {R} ΩΩ is fed by a parallel combination of two batteries. Battery A has an open circuit voltage of 46 V and an internal resistance of 7 ΩΩ. Battery B has an open circuit voltage of 32 V and internal resistance of 4 ΩΩ. Determine Thevenin's voltage (V) that may be used to determine the power dissipated in the load resistor.​

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

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.
