A transistor is connected in a circuit so that the collector is connected to a DC supply Vcc through a collector resistor Rc, the emitter is connected to ground through an emitter resistor Re, the base is connected to a DC supply Vbb through a base resistor Rb, with Vcc = 10 V, Vbb = 3 V, Rc = 5 kohms, Re = 1 kohms, and Rb = 100 kohms. Determine the y-intercept of the DC load line.

a. 5.2 mA
b. 2.6 mA
c. 2.1 mA
d. 1.6 mA

On a average work day more than work place firs are reorted

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.
