I’d love to help, but I can’t do this assignment for you so be a little more specific in the question. Like do you need a better explanation or do you need videos or something like that.

A 20 mm diameter rod made of ductile material with a yield strength of 350 MN/m2 is subjected to a torque of 100 N.m, and a bend
vodka [1.7K]

Answer:

a) 42.422 KN

b) 44.356 KN

Explanation:

Given data :

Diameter = 20 mm

yield strength = 350 MN/m^2

Torque ( T )  = 100 N.m

Bending moment = 150 N.m

<u>Determine the value of the applied axial tensile force when yielding of rod occurs </u>

first we will calculate the shear stress and normal stress

shear stress ( г ) = Tr / J = [( 100 * 10^3)  * 10 ]  /  \pi /32 * ( 20)^4  

                                       = 63.662 MPa

Normal stress(  Гb + Гa )  = MY/ I  +  P/A

= [( 150 * 10^3)  * 10 ]  /  \pi /32 * ( 20)^4   + 4P / \pi  * 20^2

= 190.9859 + 4P / \pi  * 20^2  MPa

<u>a) Using MSS theory </u>

value of axial force = 42.422 KN

solution attached below

<u>b) Using MDE  theory </u>

value of axial force = 44.356 KN

solution attached below

Which of the following types of protective equipment protects workers who are passing by from stray sparks or metal while anothe
lawyer [7]

A protective equipment which protects workers who are passing by from stray sparks or metal while another worker is welding is: E. Welding Screens.

A wielder refers to an individual who is saddled with responsibility of joining two or more metals together by wielding.

During the process of wielding, sparks and minute metallic objects are produced, which are usually hazardous to both the wielder and other workers within the vicinity.

Hence, the following protective equipment are meant to be worn or used directly by a wielder (worker) who is wielding:

  • Visors.
  • Goggles.
  • Protective clothing.
  • Dark walls.

However, a protective equipment which protects other workers who are passing by from stray sparks or metallic objects while wielder (worker) is welding is referred to as welding screens.

A five legged intersection has safety issues. in 2018, the number of crashes reported was 48 and the average 24 hour volume ente
sashaice [31]

Answer:

The crash rate is 22 vehicles per 1 million vehicles

Explanation:

In this question, we are asked to determine the crash rate per million vehicles.

Crash rate is calculated using average crash frequency.

The crash rates are calculated based on the number of crashes per million vehicle miles travelled in a year.

Mathematically;

crash rate = (48 * 1,000,000)/ [(980 + 1560 + 1230 + 900 + 1435)* 365]

= 48,000,000/(6105*365)

= 21.54 approximately 22
