Homework Statement

Hey, I'm struggling beyond belief with this assignment, one of the attached pdf's is the question and the variables given. What I'm struggling with most is what order I'm meant to do things in, I think I've got the start of it sussed but beyond that I'm clueless I've got many pages of random calculations but I'm not sure if any are correct.

The Attempt at a Solution

There are a couple of pages that I've done attached, literally have no idea if what I'm doing is correct though


Any help would be much appreciated... I'm desperate!

Not really my field but have you got the direction right for the friction force? At touch down the wheels will be pushed outwards so I expected friction to act inwards?

Edit: or are they concerned about the worse case where the aircraft is landing with side slip/crabbing? In which case you are probably right.

Hmm I'm not to sure if they are concerned with a worse case scenario, it'd make sense to me just to be safe side of things.

Hi WetFork. I am a second year SHU student on the same assignment as you. Has anyone on your course got any further with this?

Hello there,

I understand that you are struggling with your assignment on the preliminary design analysis of landing struts for a light aircraft. It can be overwhelming to figure out the correct order of steps and to ensure that your calculations are accurate. I would suggest breaking down the problem into smaller, manageable steps and following a systematic approach.

Firstly, make sure you fully understand the problem statement and the given variables. Then, start by identifying the key equations that are relevant to the problem. Make sure to double-check the units and dimensions of each variable to ensure they are consistent. This will help you avoid any mistakes in your calculations.

Next, I would recommend creating a flowchart or outline to map out the steps you need to take and the order in which you need to do them. This will help you stay organized and on track.

As you work through the problem, it is important to constantly check and verify your calculations. If you are unsure about a particular step or result, don't hesitate to reach out for help or consult additional resources. It is always better to take the time to double-check your work rather than moving forward with potentially incorrect calculations.

Lastly, I would suggest reviewing your final solution to ensure it makes logical sense and is consistent with the initial problem statement. If there are any discrepancies or uncertainties, make sure to address them and provide explanations or justifications for your decisions.

I hope this helps guide you in the right direction. Remember, it is always important to approach problems like this with a systematic and organized mindset. Don't hesitate to seek help or clarification when needed. Good luck with your assignment!
