Select all that apply Identify the statements that are true of a common-emitter amplifier if its input source resistance is very small and the emitter resistance RE=0. Multiple select question. The load resistance is a parallel combination of collector and transistor's input resistance. The terminal voltage gain is the product of the transistor's transconductance and the load resistance. The output is inverted with respect to the input. An upper limit is placed on the gain for a given external load.

b) A 20kW, 800 rpm motor has a mild steel shaft of 40mm diameter and the extension being 75 mm. The permissible shear and crushing stresses for the mild steel key are 50MPa and 110MPa. Design the keyway in the motor shaft extension. Check the shear strength of the square key against the normal strength of the shaft. Take least key width dimension to be 0.25 of shaft diameter.
