A3’ x 8’ member resists a tension force caused by the lateral wind pressure. lumber is select structural df-l. a single line of 7/8-inch diameter bolts is used to make the connection of the member. assume, cm = ct= ci = 1.0. determine the maximum axial tension load, using the lrfd method.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

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.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false
