The University of Hong Kong Department of Civil Engineering CIVL2002 M – Geology & Rock Laboratory Report Brazilian Test A. Introduction As shown by the Griffith criterion‚ tensile strength of brittle materials is theoretical 1/8 of the compressive strength. Typically‚ tensile strength of rock materials is about 1/10 to 1/8 of the compressive strength. Hence‚ rock fails easily under tension. In design‚ rock should be subjected to minimum tensile stress. Several methods

Surface Area Formulas In general‚ the surface area is the sum of all the areas of all the shapes that cover the surface of the object. Cube | Rectangular Prism | Prism | Sphere | Cylinder | Units Note: "ab" means "a" multiplied by "b". "a2" means "a squared"‚ which is the same as "a" times "a". Be careful!! Units count. Use the same units for all measurements. Examples |Surface Area of a Cube = 6 a 2

between the direction of the external magnetic field and the direction of the length of the conductor. • The force is at its maximum when the current carrying conductor is at right angles to the field (sin90=1)‚ and is zero when the conductor is parallel to the field (sin0=0). The magnitude of the force is proportional to the components of the magnetic field that is at right angles to the current carrying conductor (sin90 =1). The above points can be mathematically expressed as: F = nBILsin(0)

when radio stations broadcast. A radio wave (radiating electric field) propagates out from the source‚ traveling at the speed of light. The source‚ for example an antenna‚ creates oscillating electric(E)/ magnetic(B) fields. These fields are perpendicular not only to each other but to the direction of the traveling wave‚ and travel away from the antenna. The electromagnetic wave is‚ therefore‚ a transverse wave. The electric/ magnetic fields store the energy of the wave. Basically‚ the oscillating
