Answer:

Equlibrium is the point at the graph where supply trend intersects demand trend

Explanation:

Equilibrium by definition means "state in which opposing forces or influences are balanced"

If you are exposed to potentially infectious material via a sharps injury, what should you do immediately?

Sergio039 [100]

The correct answer is "immediately flood the area with water and clean the wound."

Further Explanation:

If someone is exposed to a potentially infectious material with a sharps item such a needle, they need to wash the area with clean water immediately. It must be a steady flow of water to get out any potential infectious material.

After flushing the injury with water, you will then wash the area or exposed skin with soap, if at all possible use a disinfectant on the area.

The person who was injured should seek medical assistance for tests to be sure that they have not been affected.

Two steel plates of 15 mm thickness each are clamped together with an M14 x 2 hexagonal head bolt, a nut, and one 14R metric pla

Blababa [14]

Answer:

a) 50 mm

b) 808.24 MN/m

Explanation:

Given:

Thickness of each steel plate = 15mm

a) To find suitable length of bolt, we'll use:

Length of bolt = grip length + height of nut

To find the grip length since there is a washer, we'll use:

Grip length = plate thickness + washer thickness

Since we have 2 plates of 15mm thickness,

Plate thickness = 15 + 15 = 30mm

Using the table, a metric plain washer has a thickness of 3.5mm

Grip length = 30 + 3.5 =33.5 mm

Height of nut: Using table A-31, height of hexagonal nut is 12.8 mm

Therefore,

Length of bolt = 33.5 + 12.8 = 46.3

Rounde up to the nearest 5mm, we'll get 50mm

Length of bolt = 50mm

b) Bolt stiffness:

Threaded length for L ≤ 125mm

LT = 2*d + 6

Where d = 14mm, from table(8-7)

= 2*14 + 6

= 34 mm

Area of unthreaded portion:

Ad= $\frac{\pi}{4} d^2 = \frac{pi}{4} * 14^2 = 153.94 mm^2$

Length of unthreaded portion in grip:

Ld = 50 - 34 = 16mm

Length of threaded portion in grip:

Lt = 33.5 - 16 = 17.5mm

Bolt stiffness = $\frac{A_d A_t E}{A_d l_t + A_t l_d}$

$= \frac{153.94 * 115 * 207}{(153.94*17.5)+(115*16)} = 808.24$

Bolt stiffness = 808.24 MN/m

Explain the Corona discharge?

rosijanka [135]

Answer:

• Corona discharge means neutralization of charge action at a sharp point

example; a pear shaped conductor, lightening conductor, van de graaf generator.

Explanation:

• In corona discharge, When a sharp conductor is placed somewhere in open space. The charges of opposite chrage attract the opposite ions in the air around that conductor.

• This increases the charge density and electric field intensity at the sharp point, this neutralises the charge at sharp point hence a discharge known as corona discharge occurs.
