Chapter 4, Problem 4.6P
Refer to the soil in Problem 4.5. Using the Casagrande plasticity chart, graphically estimate the shrinkage limit of the soil as shown in Figure 4.22.
4.5 The following data were obtained by conducting liquid limit and plastic limit tests on a soil collected from the site.
Liquid limit tests:
Plastic limit test: PL = 19.3%
a. Draw the flow curve and determine the liquid limit.
b. Using the Casagrande plasticity chart (Figure 4.21), determine the soil type.

The timber floor framing for a building comprise floor joists using 2" wide nominal lumber
is to be constructed as shown in Fig. 1. The Dead load (D) = 26 lbs./ft² (inclusive of joists
and flooring) and the live load L= 40 lbs./ft². Lateral torsional buckling is prevented for all
members and normal service conditions and temperatures are expected.
(i) Design the floor joists using 2" wide nominal lumber using Southern Pine No. 1
(ii) Design the floor beams using Caribbean Pitch Pine (Select Structural). (Assume a 8" x
14” trial section to estimate beam self-weight for your initial design). Density of
Caribbean Pitch Pine = 50 lbs/ft³ (800 kN/m³).
P12.38 WP At a point on the free surface of a stressed body, a normal stress of 64 MPa (C) and an unknown positive shear stress exist on a horizontal plane. One principal stress at the point is 8 MPa (C). The absolute maximum shear stress at the point has a
magnitude of 95 MPa. Determine the unknown stresses on the horizontal and vertical planes and the unknown principal stress at the point.
A pile group of 25 piles has to be proportioned in a uniform pattern in soft clay with equal
spacing in all directions. Assuming the value of cu to be constant throughout the depth of the
piles, determine the optimum value of spacing of piles in the group. Assume a = 0.7. Neglect
point bearing effect, and assume the piles to be circular.
