For a bronze alloy, the stress at which plastic deformation begins is 274 MPa and the modulus of elasticity is 112 GPa. (a) What is the maximum load that may be applied to a specimen having a cross-sectional area of 338 mm2 without plastic deformation? (b) If the original specimen length is 106 mm, what is the maximum length to which it may be stretched without causing plastic deformation?

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. 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]
