    Assuming that you mean a solid cone, use the standard formula for the volume of a solid, using the line y = rx/h

    This gives the distance from the vertex.
    No sorry I meant shell, not solid shapes. Also if you have time can you please assess my working?

    Yeah they could at least make it so the time has a relatively nice solution instead of like 0.317536832

    Assuming your reaction force/tension is in terms of an arbitrary angle, it's just T = 0 (when string goes slack - won't happen for a rod) or R = 0. June 13 and June 13 R is are good examples.

    Could you do me a favour and tell me which ones between 2002 and 2005 are worth doing once you get started, if it's not too much trouble?
    (Original post by samb1234)
    Leaves when R=0, then it's just a projectile question
    Thanks I got the hang of it now

    So far I've done June 2002, Jan and June 2003 and found them to be easier than last yrs exams.

    So is everyone reasonably confident? I'm getting A*'s for most papers, but some questions do give me a headache.

    How are you guys feeling?

    lol yep, fiddly. I got my script back from last year when I did M3 and it turned out that all 5 marks I lost were due to rounding errors or alike

    Looks roughly like 10/12 marks. Did you mean to put this in the STEP Prep thread?
