    Find total length of cylinder (springs, natural frequency)

    I was CWatters helped me so much! I know I feel really bad about the confusion, I probably could have worded it better but I was pretty confused myself! Thank you I'm pleased with that! Merry Christmas have a great day!

    Questions to do with crankshaft of an engine

    That makes sense now entirely! I see, thank you for all your help :) is there a way I can give you rep or something on this forum?

    Questions to do with crankshaft of an engine

    I have covered that before, but why is that the component in the direction of the conrod? the force here, mg is still the hypotenuse of the triangle right? and isn't the force down the conrod the hypotenuse?

    Questions to do with crankshaft of an engine

    Just posted all my answers to the test, got 80% but it wouldn't let me see which answers I got wrong.

    Questions to do with crankshaft of an engine

    Oh I see! That's really simple! I think I over complicated it. Thank you for all your help, I'll put the answers in some time today and let you know how I got on :) The one thing I'm still having trouble comprehending is why it is Fp*Cos(22), because i can't see why the Fp is the hypotenuse of...

    Oh wait I see how you got the cosine squared now!

    Questions to do with crankshaft of an engine

    Thank you this has helped me so much I understand it now, the only thing I am have trouble with is why is the last bit Cos(22)^2? How are the last two questions? Then they'd be all done! I think the rotational velocity one is right, not certain about the last one. Is there a way to add rep on...

    Questions to do with crankshaft of an engine

    I'm going to try and start fresh: The questions we are having troubles with: 1: Calculate the projection of the force transmitted by the piston to connecting rod AB. Give your answer in Newtons 2: Isolate crank pin OB and calculate the moment resulting from the force transmitted by connecting...

    Questions to do with crankshaft of an engine

    I know it is very confusing for me too, I'm sorry at the mess of this. It's stupid how they've done this test with the different set of questions it has made it very complicated. The first question said to find the resultant force from the pressure, so I'm pretty sure I've done that right...

    Questions to do with crankshaft of an engine

    Just looked at the question 4 again it says: Calculate the projection of the force transmitted by the piston to connecting rod AB. So you are finding the force on AB not the crank. Is the 80kN force by the piston not going to be acting as the adjacent as the angle is 22 degrees between the 80kN...

    Questions to do with crankshaft of an engine

    Actually, for Q4. I could find the angle ABO, then use the force of the connecting rod Fp cos (22) to find the adjacent of the triangle in the diagram?

    Questions to do with crankshaft of an engine

    What about the first question? Thank you for the help! Why is it cos(22)? isn't the force downwards the adjacent, because it looked like the connecting rod AB would be the hypotenuse? Q4 - I don't quite understand what it is I am supposed to do for this one, which force component am I finding...

    Find total length of cylinder (springs, natural frequency)

    I'd really appreciate it if you could take a look at my other thread, if you have the time so close to Christmas! Thanks! https://www.physicsforums.com/threads/questions-to-do-with-crankshaft-of-an-engine.788785/#post-4953803

    Find total length of cylinder (springs, natural frequency)

    Ah I see haha, well that the answer you HELPED me achieve feel promising! Thank you! I'm studying aeronautical engineering, so a bit of both!
