The following data were obtained from a consolidated – undrained triaxial compression test on a clay soil. Chamber Pressure 100 250 400 (КРа) Deviator stress @ failure 320 425 530 Pore pressure @ failure 33.5 53 140 Determine the ff: a. Undrained cohesion (95.84) b. Undrained angle of shearing resistance (15.03) c. Drained cohesion (99.19) d. Drained angle of shearing resistance (16.67)

A transit with stadia interval factor of 100.8 was set up at point C on the line between points A and B. The following readings were observed: HAIR READINGS ROD VERTICAL ANGLE UPPER MIDDLE LOWER A +15-25 1.972 1.854 1.732 В -09-07 1.330 1.175 1.010 If the distance from the instrument to the focus is 0.38m, determine the following: a) Horizontal distance between A and B. b) Difference in elevation between A and B.

Find the moment of inertia of the object about its centroid

P.16.15. A thin-walled closed section beam of constant wall thickness t has the cross-section shown in Fig. P.16.15. Assuming that the direct stresses are distributed according to the basic theory of bending, calculate and sketch the shear flow distribution for a vertical shear force S, applied tangentially to the curved part of the beam. Answer: 901 = Sy(1.61 cos 0-0.80)/r Sy 7.3 912= (0.57s² - 1.14rs +0.33²)
