The stress for tensile edge is 1.834 MPa

The stress for compressive edge is -7.945 MPa

Explanation:

Given that,

Force = 600 kN

Diameter = 0.5 m

$y=\dfrac{D}{2}=\dfrac{0.5}{2}=0.25\ m$

Distance from the centroid to the edge of the column x= 0.1 m

We know that,

Stress for column :

The stress is equal to the sum of banding stress and direct compressive stress.

$\sigma=\sigma_{b}+(-\sigma_{d})$

The value of binding stress will be positive for tensile and negative for compressive stress.

We need to calculate the stress for tensile edge,

Using formula of stress for tensile edge,

$\sigma=\dfrac{Fxy}{I}-\dfrac{F}{A}$

Put the value into the formula

$\sigma=\dfrac{600\times1000\times0.1\times0.25}{\pi\times\dfrac{(0.5)^4}{64}}-\dfrac{600\times1000}{\pi\times\dfrac{(0.5)^2}{4}}$

$\sigma=1.834\ MPa$

We need to calculate the stress for compressive edge,

Using formula of stress for compressive edge,

$\sigma=-\dfrac{Fxy}{I}-\dfrac{F}{A}$

Put the value into the formula

$\sigma=-\dfrac{600\times1000\times0.1\times0.25}{\pi\times\dfrac{(0.5)^4}{64}}-\dfrac{600\times1000}{\pi\times\dfrac{(0.5)^2}{4}}$

$\sigma=-7.945\ MPa$

Hence, The stress for tensile edge is 1.834 MPa

The stress for compressive edge is -7.945 MPa

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.

Idon't see any answer choices for your question, but the answer would to highlight the box, and drag the box to the box of choice (or do a simple copy and paste, and delete the old data).
