A rigid, insulated vessel is divided into two compartments connected by a valve. Initially, one compartment, occupying 1.0 ft³, contains air at 50 lbf/in², 675°R, and the other, occupying 2.0 ft3, is evacuated. The valve is opened and the air is allowed to fill both volumes. Assume the air behaves as an ideal gas and that the final state is in equilibrium. Determine the final temperature of the air, in °R, and the amount of entropy produced, in Btu/°R. Step 1 Your answer is correct. Determine the final temperature of the air, in °R. T₁= 675 Hint °R

What is the Shear Force,V?

A cable is connected to an L shaped arm OAB as shown. The magnitude off the tensile force on the cable is given as T = 2500 and angle between the segment AB of the L- shaped arm and cable = 91.229 degrees. ( use the vector approach ) A) determine the components of the tensile force on the cable which are parallel and perpendicular to segment AB of the L-shaped arm

6) Find the centroid, (x, 5), of the area below. The circle and semi-circle are holes. The circle has a diameter of 0.5 m, is tangent to the x-axis, and is centered with the x = 0.5 m mark. The semi-circle has a radius of 0.15 m and is centered with the x = 1.5 m mark. y2 = x -y +x = 2 1 m 1m 1 m
