2. The following results were obtained at failure in a series of three drained triaxial tests on fully saturated clay specimens originally 38 mm diameter by 76 mm long. Determine the values of effective shear strength parameters c' and φ'. (Do not perform area corrections). All-round pressure σ3 (kPa) 200 400 600 Axial compression (mm) 7.22 8.36 9.41 Axial load (N) 480 895 1300 Volume change (cc) 5.25 7.40 9.30

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?

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
