Differences between triaxial test and shear box test?
Shear box tests are generally suitable for cohensionless soil except fine sand and silt whereas triaxial test is suitable for all types of soils. Pressure changes and volume changes can be measured directly in triaxial test which is not possible in shear box test. Pore water pressure can be measured in the case of triaxial test which is not possible in direct shear test. Triaxial machine is more adaptable. The stress distribution across the soil sample in the failure plane is more uniform in triaxial test. The complete state of stress is known at all intermediate stages up to failure during the triaxial test whereas only the stress at failure are known in the direct shear test. In triaxial test, there is complete control over the drainage conditions, where control of drainage conditions is very difficult in shear box test.
Which of the following is an example of a triaxial joint?
Ball-and-socket joint is an example of triaxial (or multiaxial) joint.
What is the neeed of extensometer?
it is used to measure the extension or compression in the object after it is subjected to tension or compression test it is used to measure the extension or compression in the object after it is subjected to tension or compression test
How do you check cylinder compression 95 Chevy s10 4-cylinder and what is normal?
A box compression tester is a machine that measures the size and quality of boxes. It uses a variety of techniques to test the strength, durability, and compression of boxes. The box compression tester can also be used to test the strength and compression of packaging materials. Most manufacturers use this type of machine to test the quality of the boxes they use to ship their products.
When doing a compression test on a gas engine do you start the engine?
No, The compression test is done as the starter cranks the engine
What is consolidated drained triaxial test?
In a consolidated drained test the sample is consolidated and sheared in compression with drainage. The rate of axial deformation is kept constant, i.e. is strain controlled. The idea is that the test allows the sample and the pore pressures to fully consolidate (i.e. adjust) to the surrounding stresses. The test may take a long time to allow the sample to adjust, in particular low permeability samples need a long time to drain and adjust strain to stress level
What is triaxial stress?
That is stress in three dimensions. Biaxial stress is in two dimensions. Triaxial stress has normal and shear stresses along each of three planes. Most beams can be analyzed with uniaxial stress; plates with biaxial; solids with triaxial
How do the procedures used in subsoil investigation provide information for the design of substructures?
Subsoil investigations provide a clear idea of the type of soil you have in the area you are building on. There are a few tests that are conducted to show this: - Moisture content- Atterberg limits- Sieve Analysis- Triaxial Compression Test- Consolidation test- Bulk density- Dry density- Specific gravity- Chemical testsThese will all show the Architect what materials he will need to build on this land and the type of foundation to use to stop the building from sloping or sinking into the ground
What are typical compression test reading for a diesel engine in good condition?
typical compression test reading fora diesel engine
What are the difference between result obtained from ultrasonic test and triaxial test?
Triaxial testing will yield static strength properties of the material while ultrasonic measurements will give dynamic strength properties. The two can be related to each other by using various relationships between Young's Modulus, Bulk Modulus, Shear Modulus and Poisson's ratio. Static results should be lower than the dynamic results.
How many compression strokes during a compression test?
3 - 4 per cylinder.
What is dry and wet compression test in a vehicle?
A dry compression test measures the pressure inside the cylinders of an engine with the fuel supply disconnected, while a wet compression test involves introducing oil into the cylinders to test for issues such as worn piston rings or valves. Wet compression tests can help determine if low compression is due to piston ring or valve issues, while dry compression tests are often used for a baseline measurement of engine health.
