A 5 lb force is applied to the handles of the vise grip. Determine the compressive force developed on the smooth bolt shank A at jaws. a) Draw free-body diagrams of members ABD, ABE, ECG and CD. b) Use FBD of member ECG to find force on member CD and force at joint E. c) Use FBD of member ABE to determine the forces at A and joint B

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]
