ryan lang Posted October 3, 2011 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

Steve GT Posted October 3, 2011 Posted October 3, 2011 i used to rule at trigbut i was 14 and 8 years later I've turned thick so cant help you out anymore Quote
ryan lang Posted October 3, 2011 Author Posted October 3, 2011 ive never been any good at maths, and they spring this 1 on me after 2 lessons :/ lol Quote
lukEp Posted October 3, 2011 Posted October 3, 2011 Ryan this is some crazy stuff to get my head around againBloody SINE, COSINE and TANGENTS. I remember doing this and still have the assignments on a dongle somewhere I'll try dig them out. Quote
Hou Posted October 3, 2011 Posted October 3, 2011 Its too late for my brain to work, I did Pure maths with mechanics and physics at A level 9 years ago Quote
Matt1878 Posted October 3, 2011 Posted October 3, 2011 I was gonna go pull my finger out and go back to college to do this course and this kinda put me off haha!! Nah only kidding... is it good though? Quote
templar2007 Posted October 3, 2011 Posted October 3, 2011 I saw this and thought ya I am ok at maths and it when way over my head Lmao Quote
ryan lang Posted October 3, 2011 Author 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
Shahzad Posted October 4, 2011 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
ryan lang Posted October 4, 2011 Author Posted October 4, 2011 no fancy shite lol just straight wheels and a full turn i think dude Quote
Shahzad Posted October 5, 2011 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
5T4R7ET N/A Posted October 5, 2011 Posted October 5, 2011 hypotenuse calculatorhttp://easycalculation.com/trigonometry/triangle-angles.phppythagoras calculater http://www.carbidedepot.com/formulas-trigright.aspjust gotta know where to put the data in.Can u give us any more info?? Quote
ryan lang Posted October 5, 2011 Author Posted October 5, 2011 its all good now thanks mate, managed to do most of it, then he told us something that we had to do that he didnt say last week lol Quote
