Question: The rigid jointed steel frame with a fixed base at support A has to carry both the dead and live loads shown in Figure P7.46. Both the column and the girder are constructed from the same size members. What is the minimum required moment of inertia of the frame members if the vertical deflection at D produced by these loads cannot exceed 0.5 in.? Use E = 29,000 ksi.
A thin 100 cm long and 10 cm wide horizontal plate is maintained at a uniform temperature of 150oC in a large tank full of water at 75oC.
An air nozzle has an exit area 1.6 times the throat area. If a normal shock occurs at a plane where the area is 1.2 times the throat area, find the pressure, temperature, and Mach number at the exit. The stagnation temperature and pressure before the..
1. Refer to Problem 3.19. Using Eq. (3.51), determine the variation of the relative density with depth. Use Qc 5 1.
find the stiffness of the isolation pad if the maximum permissible values of deflection and acceleration of the instrument are specified as 10 mm and 20g, respectively.

The open-loop gain A of real (nonideal) op-amps is very large at low frequencies but decreases markedly as frequency increases. As a result, the closed-loop gain of op-amp circuits can be strongly dependent on ω = 4 × 103 rad/s determine
another guide recommends 12700 lbhr water flowrate through 2 pipe and says that this will give 16 water friction
The procedure to inflate a hot air balloon requires a fan to move an initial amount of air into the balloon envelope followed by heat transfer from a propane burner to complete the inflation process.
Determine all force components that the 20-tooth pinion applies to the 50-tooth gear. Make a sketch showing these forces applied to the gear.
In the casting of steel under certain mold conditions, the mold constant in Chvorinov's Rule is known to be 4.0 min/cm2, based on previous experience. The casting is a flat plate whose length = 35 cm, width = 10 cm, and thickness = 15 mm. Determine h..
