Circular bar 1 is attached to the wall by brackets 2 and 3. Bracket 3 is supported by a pin joint at F. Bracket 2 is attached to bracket 3 by bolt assemblies. Bar 1 is subjected to an external load of 5000 N (weight of the bar is negligible). Bracket 2 weighs 400 N and bracket 3 weighs 300 N. Bar 1 is made of a material which can withstand a maximum normal stress (sigma) =10 MPa and the bolted connections are made of material which can withstand a maximum shear stress ….

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

What is the main objective of using reheat rankine cycle?

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
