For a hollow round tubing with outer diameter do= 6 in and wall thickness t= 0.25 in that is welded to a plate with a fillet weld size ℎ = 0.25 in and weld strength sweld = 50 ksi, assume that failure occurs only in the weld. for the following loading conditions calculate the allowable force or moment before failure:
a.) axial loading, calculate fallow[#]
b.) pure bending, calculate mallow [in#]
c.) pure torsion, calculate tallow [in#]

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

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?

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
