yeah that picture is invalid to your point you are proving mine there, The last picture shows a drilled hole, that has been threaded and sectioned, but no bolt is inside (as the end of a bolt with thread makes 45 degree angle) so yeah you dont section ENGAGED thread you section NON engaged thread
8. You aren't supposed to section thread that is engaged, so it cant possibly be A, C has no end to the bolt, D have no thread even on the bolt and B has unsectioned thread on the bolt and sectioned thread for the unused part in the drilled hole. So.... its B
for 10. did you develop expressions for sum of forces horizontal and vertical and then solve simultaneously?
Because when you do you find the value for N in terms of P and sub it in to the other and can then make P the subject and get the answer of D
also P needs to be broken down into two...
this question i loved it, You graphically do it, draw a straight line down, lift is perpendicular to the drag and thrust so it is 75 degrees to the horizontal, and then connect up the two at a gap of 1600N to your scale this then can be measured or used with trig, I got a weight of the glider of...
In my opinion this is the longest most stretched for time exam you can't realistically complete it while putting in your best attempt you have to scrafise your self in certain areas just to complete the paper, so pissed off I didnt even get to finish the second 5 mark drawing :(
The theory was...
