I believe that y is the distance from the neutral axis (40mm) and m is the maximum bending stress? But m is not given is it? Do I have to transpose the formula to find m?

Homework Statement The second moment of area of the beam shown about the neutral axis X X is 4x10^6mm^4 Find the maximum bending stresses, tensile and compressive, set up in a beam of this section 2.6m long and simply supported at its ends and carrying a concentrated load of 4.8kn at its mid...

this was incredibly helpful, I understand it and just needed my mind refreshing so thanks, in terms of the second one how do you substitute the identity? Is this a given formula or do you need to transpose it to find it yourself? Can you do the same working for the first part of the second...

Can anybody please help me solve this? 4cot² - 6 cosec x = -6

To be honest I'm lost with it all, I havnt done it in years and I'm hoping to start university soon so was just looking at refresher questions

Can anybody please help me solve either of these equations Solve the following equation for angles between 0 and 360 degrees 4cos²θ + 5sinθ = 3 4cot² - 6 cosec x = -6

I see, and where do you go after that? It's been an awful long time since I've done any of this and i just want to refresh my memory

I have absolutely no idea how to tackle either of these questions Solve the following equation for angles between 0˚ and 360˚ to 2 decimal places 4cos²θ + 5sinθ = 3 4 cot² - 6 Cosec x = -6

struggling to remember anything about partial fractions, can anybody help me with this? 6x-5 (x-4) (x²+3)

Did you ever find the correct solution to this question? I am currently stuck on the same one
