The inlet for a high-bypass-ratio turbofan engine has an area A1 of 6.0 m 2 and is designed to have an inlet Mach number M~ of 0.6. Determine the additive drag at the flight conditions of sea-level static test and Mach number of 0.

An intersection had 13 crashes last year. The 4 legs of the intersection had 2-way ADT values of 9671, 2893, 9506, and 2611 vehicles last year. Calculate the RMEV for this intersection?

When is it appropriate to model a structural element as a beam?

A hanging wire made of an alloy of nickel with diameter 0.19 cm is initially 2.8 m long. When a 59 kg mass is hung from it, the wire stretches an amount 0.286 cm. A mole of nickel has a mass of 59 grams, and its density is 8.90 g/cm3.

If the middle bend of a three-bend saddle is a 30-degree bend

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.
