In an orthogonal cutting operation, the rake angle = -8°, chip thickness before the cut = 0.22 mm and width of cut = 3.2 mm. the cutting force is 1750n and the thrust force is 1200n. the chip ratio = 0.42. determine: a-the chip thickness after the cut (b)-shear angle (c)-coefficient of friction (d)-friction angle (e)-shear strain.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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?
