Answer:
(b)Distortion energy theory.
Explanation:
The best suitable theory for ductile material:
(1)Maximum shear stress theory (Guest and Tresca theory)
It theory state that applied maximum shear stress should be less or equal to its maximum shear strength.
(2)Maximum distortion energy theory(Von Mises henkey's theory)
It states that maximum shear train energy per unit volume at any point is equal to strain energy per unit volume under the state of uni axial stress condition.
But from these two Best theories ,suitable theory is distortion energy theory ,because it gives best suitable result for ductile material.
Answer:
a)
, b)
, c) 
Explanation:
A turbine is a steady-state devices which transforms fluid energy into mechanical energy and is modelled after the Principle of Mass Conservation and First Law of Thermodynamics, whose expressions are described hereafter:
Mass Balance

Energy Balance

Specific volumes and enthalpies are obtained from property tables for steam:
Inlet (Superheated Steam)


Outlet (Liquid-Vapor Mix)


a) The mass flow rate of the steam is:



b) The exit velocity of steam is:




c) The power output of the steam turbine is:



Answer:
C. underground road
Explanation:
Generally compound curves are not filtered and recommended for use in an underground road. However, they are best used in the road, water way, and rail way.
Answer:
The industrial systems of the future are seen as complex systems, composed of vast numbers of devices, interacting with each other and with enterprise systems continuously.
summary:
they are related because they ARE a system. well, a type.
hope this helps!! :)
