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 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 […]
