1. Every installation is to be properly protected near the point of entry of supply cables by a two-pole linked main switch and a fuse unit. In a two-wire installation if one pole is permanently earthed, no fuse, switch or circuit breaker is to be inserted this pole. A 3-pole switch and fuse unit is to be used in 3-phase supply.

2. The conductor used is to be of such a size that it may carry load current safely.

3. The conductors installed are to be safe in all respects.

4. Every sub-circuit is to be connected to a distribution fuse board.

5. Every line (phase or positive) is to be protected by a fuse of suitable rating as per requirements.

Define denial and identify three of your own examples of denial (they can be from your own life or someone else's). In 300 words

Fantom [35]

Answer:

Denial is a defense mechanism which allows an individual not to accept the truth about a painful experience or distress.

Denial is a defense mechanism used to protect oneself against accepting a painful experience or situation in life.

Denial could be helpful or harmful.

It can be helpful when one begin to take action about a problem by seeking for help.

It could be harmful if you don't seek for help when in distress.

A person engaged in denial is trying to stay sane and act normal like everything is alright with he/she. The person tries to block negative thought and focus on more positive thoughts.

Example of denial

1) A young lady who just experienced a breakup from her boyfriend who she truly loves but act like the breakup doesn't affect her or that she doesn't love the guy.

2) A 21 year old person who has cancer and has about 10 months to live have plans of celebrating his/her 25th birthday in a big way

3) When someone is harboring the thought that coronavirus is not real or it is not a serious disease.

What is the magnitude of the maximum stress that exist at the tip of an internal crack having a radius of curvature of 1.9 x 10-

Hitman42 [59]

Answer:

2800 [MPa]

Explanation:

In fracture mechanics, whenever a crack has the shape of a hole, and the stress is perpendicular to the orientation of such, we can use a simple formula to calculate the maximum stress at the crack tip

$\sigma_{m} = 2 \sigma_{p} (\frac{l_{c}}{r_{c}})^{0.5}$

Where $\sigma_{m}$ is the magnitude of he maximum stress at the tip of the crack, $\sigma_{p}$ is the magnitude of the tensile stress, $l_{c}$ is $1/2$ the length of the internal crack, and $r_{c}$ is the radius of curvature of the crack.

We have:

$r_{c}=1.9*10^{-4} [mm]$

$l_{c}=3.8*10^{-2} [mm]$

$\sigma_{c}=140 [MPa]$

We replace:

$\sigma_{m} = 2*(140 [MPa])*(\frac{\frac{3.8*10^{-2} [mm]}{2}}{1.9*10^{-4} [mm]})^{0.5}$

We get:

$\sigma_{m} = 2*(140 [MPa])*(\frac{\frac{3.8*10^{-2} [mm]}{2}}{1.9*10^{-4} [mm]})^{0.5}=2800 [MPa]$
