Why fracture strength of ceramic materials increases with decreasing specimen size? (b) The fracture strength increases with decreasing specimen size because as specimen size decreases, the probably of the existence of a flaw of that is capable of initiating a crack diminishes. Why is it that measured fracture strengths of most materials are much lower […]
What is meant by strain hardening?
What is meant by strain hardening? Work hardening, also known as strain hardening, is the strengthening of a metal or polymer by plastic deformation. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material. What is strain hardening in stress strain curve? The metal must be plastically deformed […]
What is the cost to society for underage alcohol use per year?
What is the cost to society for underage alcohol use per year? The cost to society for underage alcohol use is more than $ 200 per year for every man, woman and child in the United States. Underage drinking,costs Americans nearly $60 billion, amounting to the equivalent of $200 for every man, women and child […]
What are true about algorithms?
What are true about algorithms? An algorithm is a well-ordered collection of unambiguous and effectively computable operations that when executed produces a result and halts in a finite amount of time [Schneider and Gersting 1995]. Algorithms have unambiguous operations. Algorithms have effectively computable operations. Algorithms produce a result. Can algorithms perform logical operations? Algorithms are […]
When velocity potential φ exists the flow is?
When velocity potential φ exists the flow is? If velocity potential (Φ) exists, the flow must be irrotational. 2. When velocity potential exists in a flow it means? If there exists velocity potential, then the fluid flow is rotational. If the given velocity potential satisfies the Laplace equation (Eq. 4), then the fluid flow is […]

How does steam turn a turbine?
How does steam turn a turbine? As the name implies, a steam turbine is powered by steam. As hot, gaseous steam flows past the turbine’ spinning blades, steam expands and cools, giving off most of the energy it contains. This steam spins the blades continuously. The blades thus convert most of the steam’s potential energy […]
What is the difference between thermoplastics and thermosetting plastics?
What is the difference between thermoplastics and thermosetting plastics? Thermosoftening (also called thermoplastics) are plastics which will soften when heated and can be reshaped. Thermosetting plastics are plastics do not soften on heating. What is the difference between thermoplastic and thermosetting plastics Class 8? Thermoplastics : – Plastics which have a linear arrangement of molecules […]
How do we know if a star is moving toward or away from us?
What is heat transfer analysis?
What is heat transfer analysis? The Heat transfer simulation type allows the calculation of the temperature distribution and heat flux in solids under thermal loads (for example, convection and radiation). Both steady-state and transient simulations are supported. What is the most common type of heat exchanger used in the process industries? The shell-and-tube heat exchanger […]
