I learnt stresses in a stepped bar

# data[].attributes.body
I have learnt how to use the formulas on calculating the maximum stress and total change in length.

# data[].attributes.body
I learn to do maximum stress n extenteded len

# data[].attributes.body
I have learn how to use the max stress formulas and total extension will put into good use

# data[].attributes.body
Today I have learn a Step Bar formula for Maximum Stress and Tensile Strength.

# data[].attributes.body
Maximum tensile stress
Finding the total change in extension

# data[].attributes.body
I learn about new topics which is step bar. I learn all the new formula and also how to do.

# data[].attributes.body
i’ve learnt how to calculate the maximum stress of the bar and how to calculate the total change in length/extension (x) also the maximum tensile stress of the the stepped shaft.

# data[].attributes.body
I learnt how different formula work

# data[].attributes.body
step bar uh sia

# data[].attributes.body
We learned new formulas for mechanics, specifically the formulas for step bar.

# data[].attributes.body
i learnt steb bar thingy

# data[].attributes.body
I learn how to use and apply the formula

# data[].attributes.body
Today I learned about Mechanics but to be specific we did a test and a recap about last lesson which is of stress, strain, Young Modulus, Extension, Compression, Area of a round bar, Area of a hollow bar and Area of a rectangle. We did a quick recap and then we learned how to solve a question and learned how to find the maximum stress and the total extension of a round bar using the formulas we learned from the last lesson.

# data[].attributes.body
The formula is easy to understand if you could do that question paper

# data[].attributes.body
I learn about Step Bar.I also learn how to calculate maximum strees of the bar and calculate the overall change in length.
