ozzi3 years ago
8 0

Answer:

True

Explanation:

For point in xz plane the stress tensor is given by\left[\begin{array}{ccc}Dx_{} &txz\\tzx&Dz\\\end{array}\right]

where Dx is the direct stress along x ; Dz is direct stress along z ;  tzx and txz are the  shear stress components

We know that the stress tensor matrix is symmetrical which means that tzx = txz  ( obtained by moment equlibrium )

thus we require only 1 independent component of shear stress to define the whole stress tensor at a point in 2D plane

What is HEX? <br><br> Need help in Computer Programming
ser-zykov [4K]

Hexadecimal is a base16 way of representing numerical values in a way a human can remember, it is not easier for the computer to read it but it is for a human. Hex can have both letters and numbers, as soon as the binary value gets above 9 it is replaced with a letter. Numbers are used from 0 to 9 and letters are used between binary values 10 and 16, hex does not go above 16 instead it just simply gets another digit.

For example, if there is a hex code of D9 then in decimal, it represents the number 139.

Hope this helps!

Why does the dead man switch kill the robots manual action when pressed to hard or released
Arturiano [62]

Answer:Why does the dead man switch kill the robot's manual actions when released or pressed to hard? This is because when something goes wrong, say that the robots hits you upside the head, your reaction is either to let go or grip the switch too tight, thus the reason these actions stop all movements

Aerospace engineers who work for certain government agencies are often required to have security clearance. Explain two reasons
yuradex [85]

Answer:

Two reasons that justify the requirement for security clearance for aerospace engineers working for government agencies are;

1) Such engineers have access to data regarding the blueprint, components, method of construction, functionality status, new systems design, future systems design, inventory of systems and aeronautical systems database which are sensitive information that are of high importance to the federal government

2) Such engineers take part in the testing of aeronautic equipment, and will require security clearance to be able to input data results into the data base of the aeronautic equipment

The concrete canoe team does some analysis on their design and calculates that they need a compressive strength of 860 psi. They
vlada-n [284]

Answer:

874 psi

Explanation:

Given a sample mean (x') = 900,

and a standard error (SE) = 10

At 99% confidence, Z(critical) = 2.58

That gives 99% confidence interval as,

x' ± Z(critical) x SE = 900 ± 2.58 x 10

The value of the lower limit is,

900 - 25.8 = 874.2

≈ 874 psi
