Answer:
1) 75Mpa
2) 1.125 MPa
Explanation:
given data:
gauge length = 4 mm
displacement 
a) structural steel
Young modulus for steel is 
we know that


= 75Mpa
b) PMMA
Young's modulus 

stress = 1.125 MPa
Answer:
peak flow and any engineering considerations related thereto
Explanation:
It should be no surprise that a peak flow meter will report peak flow, sometimes with important maximum-value, time-constant, or bandwidth limitations. There are many engineering issues related to flow rates. A peak flow meter can allow you to assess those issues with respect to the flows actually encountered.
Peak flow can allow you to assess adequacy of flow and whether there may be blockages or impediments to flow that reduce peak levels below expected values. An appropriate peak flow meter can help you assess the length of time that peak flow can be maintained, and whether that delivers sufficient volume.
It can also allow you to assess whether appropriate accommodation is made for unexpectedly high flow rates. (Are buffers or overflow tanks of sufficient size? Is there adequate protection against possible erosion? Is there adequate support where flow changes direction?)
Answer:

Explanation:
We understand that the sum of the pressures in the tank and the pump is equal to that of the Nozzle,
In this way,

For the pressure we also know that it is given by


So,



Answer:
Maybe when there is a fire there can be fire drones that can take it out. and it can also resuce people who are stuck there.
