Based on your recommendation, the company changed their material but selected a material, which was irrelevant to your suggestion due to cost. They begin to produce forging die made of D3 tool steel but it fractured after only a short service life. The cause of the failure was found to be severe carbon segregation. A client has asked for your recommendation for correction of this problem. In response to this request, please address the topics (a) to (c) first and then provide your recommendation.

Fluids at rest possess no flow energy. a)- true b)- false

Find the kinematic pressure of 160kpa. for air, r-287 j/ kg k. and hair al viscosity of air at a temperature of 50°c and an absolute (10 points) (b) find the dynamic viscosity of air at 110 °c. sutherland constant for air is 111k

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
