Answer:
1.4 psi
Explanation:
Before diving into the solution to the question above, let's pick out the parameters needed in solving this problem from the question.
=> The measurement for the outer diameter of the balloon = 20 inches, the measurement for the thickness = 0.012 in, the allowable tensile stress = 1ksi and the allowable shear stress in the balloon = 0.3 ksi.
The first thing to determine is the inner diameter = 20 - 2 × 0.012 in = 19.976 in.
Therefore, the tensile stress:
1000 = k × [19.976/2]÷ 2 × 0.012 = 2.4 psi.
Also, the sheer stress which is also the maximum permissible pressure in the balloon can be calculated below as:
0.3 × 1000 = k × [19.976/2]/ 4 × 0.012 = 1.4 psi.
Answer:
new ArrayList<Thing>()
Explanation:
The syntax to declare an arrayList is:
ArrayList [var-name] = new ArrayList<data-type>()
From the question;
We understand that the variable name is: a
And the data-type is: Thing
So, the ArrayList of type Thing can be defined using:
ArrayList a = new ArrayList<Thing>();
Hence:
None of the options answers the question.
Answer:
zero off your workpiece so you can work from a datum, usually the centre of your work on a lathe. change your tool to a drill and drill a hole to a size smaller than your thread diameter, change out your tool for a threaded tap and away you go.
I'm not sure which part they want but I'd say ensure your tool is set to the right height, you have the tool lines up where you want to cut and that you have calculated the speed you need to cut at safety. Drill a hole before you tap though.
If you have a CNC lathe you just set the programme to do the processes and tool change for you.
I would enjoy working in a shelter because of the animals and I would also enjoy working as someone who interviews murderers because I find it interesting
I wouldn’t want to work in fast food because of all the grease and I wouldn’t want to work as a cop because of all the dangerous situations you could get into.
