Which of the 2 scenario flights will result in a longer flying time, or will they fly the same Scenario 1. span of 0.225 m and a chord of 0.045 m with a weight of 0.0500 Newtons and the LER is 0.2025

Scenario 2. span of 0.245 m and a chord of 0.045 m. the weight is 0.0523 newtons. so the LER is 0.2108

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

What is creep? what is stress relaxation?

Estimate the change in specific internal energy au and specific enthalpy h from inlet to outlet for ethylene glycol (a liquid) flowing through each of the following devices: (a) a heat exchanger where the glycol temperature increases from 20 °c to 80 °c; (b) a pump operating at about 25 °c and increasing the glycol pressure from 100 kpa to 8 mpa.
