A60% strain rosette mounted at point on the surface of the bracket gives the following readings: εa= 780 (10)^-6 εb=400 (10)^-6, and εc=500 (10)^-6. determine: (a)- the principal strains, and (b) the maximum in-plane shear strain and associated average normal strain. in each case show the deformed element due to these strains.

On a average work day more than work place firs are reorted

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
