A force of 5000n is applied outwardly to each end of a 5. 0-m long rod with a radius of 34. 0 cm and a young's modulus of 125 ×

Vitek1552 [10]

The elongation of the rod is $5.51 \times 10^{-4}m$ `

<h3>Young Modulus of a substance</h3>

The young modulus of a substance is the<u> ratio of stress to the strain</u> of material.

$Modulus = \frac{Stress}{Strain}\\ Modulus =\frac{Fl}{Ae}$

where:

F is the applied force = 5000N
l is the length of the rod = 5.0m

A is the cross-sectional area = $\pi r^2 = 0.34^2 * 3.14 =0.362984m^2$

Required

Extension of the rod "e"

Substitute the given parameters into the formula to have;

$e=\frac{Fl}{A \gamma} \\e=\frac{5000 \times 5}{0.362984 \times 125,00,000}\\e=\frac{25000}{45,373,000}\\e= 5.51 \times 10^{-4}m$

Hence the elongation of the rod is $5.51 \times 10^{-4}m$ `

Further Explanation:

There are numerous grants and opportunities for the nursing profession for minorities. There are several educational scholarships for minorities to get an education in nursing. Some of the scholarships that were available in 2019 were;

The Jackie Robinson Foundation Scholarship
Barbara Rhomberg Excellence in Nursing Scholarship.
Johnson and Johnson/AACN Minority Nurse Faculty Scholars Program
Minority Nurse Magazine Scholarship Program
AETNA/NCEMNA Scholars Program

There are a shortage of nurses and this career field is expected to need more nurses each year. It is a great opportunity for all people including those of minorities.

Which of the following is maximum in the principal plane.

Maurinko [17]

The only option that can attain a maximum in the principal plane is; A: Normal stress

The options are missing and they are;

a) Normal stress b) Shear stress c) Shear strain

Now, in beams sections or when dealing with rectangular sections subject to bending stresses and strains, there is what we call a principal plane and this principal plane is defined as the plane at which maximum stress occurs at an angle of 45°.

Now, the principal plane is also defined as the plane at which the normal stress attains maximum and minimum values while the shear stress here is zero.

In conclusion, the only one that can attain a maximum in a principal plane is normal stress.
