Question 4 A sample of soft silty clay from the Thames Estuary is taken from the ground, trimmed to a cylindrical specimen and then placed into a triaxial cell. The sample is compressed isotropically under drained conditions by increasing the cell pressure in the triaxial cell to 450 kN/m², with a back (pore) pressure of 200 kN/m2. At the end of the compression stage the sample is calculated to have dimensions of length = 74.03 mm and diameter = 37.17...

2. A rectangular beam, 400 x 600 mm gross dimension, is cast using a concrete strength of fc 30 MPa, reinforced with 5-25 mm diameter steel bar at the effective depth of 500 mm. If is subjected to a moment, M 130 kN-m. Determine the following: Magnitude of the bending moment that cracks the singly-reinforced beam section. (10 pts) b. For the computed cracking moment, determine the maximum compressive stress in the concrete and the stress in the tension steel....

L/2 L/4 L/2 L/4 P/2 P/2 3 pt. Loading 4 pt. Loading 1. The schematics above show two common mechanical testing geometries - a 3 point loaded specimen and 4 point loaded specimen. The samples you would test in these geometries would be called "flexure" samples. P is the load measured by the load cell Samples would actually be longer than L but the contact points determine the loading profile...
