A light bar AD is suspended from a cable BE and supports a 20-kg block at C. The ends A and D of the bar are in contact with fri

babymother [125]

Answer:

Tension in cable BE= 196.2 N

Reactions A and D both are 73.575 N

Explanation:

The free body diagram is as attached sketch. At equilibrium, sum of forces along y axis will be 0 hence

$T_{BE}-W=0$ hence

$T_{BE}=W=20*9.81=196.2 N$

Therefore, tension in the cable, $T_{BE}=196.2 N$

Taking moments about point A, with clockwise moments as positive while anticlockwise moments as negative then

$196.2\times 0.125- 196.2\times 0.2+ D_x\times 0.2=0$

$24.525-39.24+0.2D_x=0$

$D_x=73.575 N$

Similarly,

$A_x-D_y=0$

$A_x=73.575 N$

Therefore, both reactions at A and D are 73.575 N

An engineer is applying dimensional analysis to study the flow of air through this horizontal sudden contraction for the purpose

navik [9.2K]

Answer:

The answer is " $\Delta p = f(V1, p, V2, d, D, L)$ "

Explanation:

Please find the complete question in the attached file.

Its change in temperature in pipes depends on rate heads and loss in pipes owing to pipe flow, contractual loss, etc.

The temperature change thus relies on V1 v2 p d D L.

<h3>What is PPE?</h3>

PPE is an acronym for personal protective equipment and it can be defined as a terminology that is used to denote any piece of equipment which is designed and developed to offer protection to different parts of the body while working in a potentially hazardous environment.

Some examples of personal protective equipment (PPE) that are used to protect the different parts of the body include the following:

Respirators
Face mask
Face shield
Gloves
Boots
Helmet

In conclusion, respiratory protection <u>provides fool proof protection</u> against fumes and gases during wielding.
