The wrench blanks, and the final wrench produced with the CNC machine, will be made from 6061-T6 aluminum alloy. With a factor of safety of 2, determine (i) the maximum force that can be applied to the handle, and (ii) the maximum torque produced by the wrench in tightening a bolt, both before yielding will occur. Draw a FBD of the wrench when you do the calculations.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

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?
