ryan lang Posted October 3, 2011 Share Posted October 3, 2011 just recently started level 2 light vehicle repair and maintenance at college, but ive been fast tracked a year. right so ive now got some maths homework to be in at the end of this week, problem being, im shit at maths...its trigonometry related to a car, but i havent got a clue how to set it up so i can work it out :/the question is:a vehicle has a wheelbase of 3.0m and a track of 1.8m. when the vehicle is turning through a certain radius, the steering angle of the inner wheel is 25 degrees. using trig, calculate:the angle of the outer wheel the length of the turnnow i think i could work it out if i had the triangles set out with the 3 values above on them, but i have to set the triangles out myself and put the angles and lengths on the triangle and this is where i get stuck if any 1 could shed any light on how to start it i would be really greatful random thread i know, but dont know where to ask lol Quote Link to post Share on other sites

ryan lang Posted October 3, 2011 Author Share Posted October 3, 2011 i know, i havent done it in something like 5 years, and i was never any good at it loli know how to work it out, but i dont know how to set it up if that makes any sense to you guys?like if the triangle was infront of me with the 3 values on, id be able to work it out, but i have no idea how to set the question up on paper to do the formula's and thatand yeah matt its good, apart from the maths :/ Quote Link to post Share on other sites
Shahzad Posted October 4, 2011 Share Posted October 4, 2011 HiI need more information. Do the steering wheels have any toe out? Are we assuming true Ackerman or anti-Ackerman geometry? What is meant by 'length of turn', and do we have the given radius? Quote Link to post Share on other sites
ryan lang Posted October 4, 2011 Author Share Posted October 4, 2011 no fancy shite lol just straight wheels and a full turn i think dude Quote Link to post Share on other sites
Shahzad Posted October 5, 2011 Share Posted October 5, 2011 I tried to work it out but i must be doing somthing wrong because im getting a -ve answer.Sorry i could not help as the question is too vague Quote Link to post Share on other sites
