The first 25 mm section of a pin shaped fin with a diameter of 5 mm, a length of 50 mm and a heat conduction coefficient of 100 W/m-K is insulated. The remaining 25 mm part is in contact with air whose temperature is 20 °C and the heat transfer coefficient is 500 W/m2-K. The wall temperature to which the end of the insulated part of the fin is connected is given as 100 °C. The other end, whose temperature is 100 oC, has a thermal resistance of 4x10-4 m2-K/W at the interface. Calculate the temperature at the midpoint of this fin.

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
