Acantilever of length 0.5 m and square cross-section of sides 50 mm is subjected to a downward-acting alternating end load. the static tensileield s for completely reversed stress of the material are(300 ? if the mean stress ? m-30 mpa, using the soderberg-equation. and f a. an determine the maximum and minimum values of the end load. also show stress-time variation curve (sinusoidal).

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
