Did we require to scale the horizontal distance measured from the image with a ruler according to the vertical distance stated ?? For the projectile problem..

Well I'm not sure but i used the same scale for range which i used in part a to get vertical height
Ok what did u guys do for probably the most toughest ques..which stated how would the angle theta affect the forces inward or something for the poles (5 marks QWC Question)...expecting to lose all the marks out of it 😢

Increase in theta increases vertical component and decreases horizontal component and over all magnitude of force Also decreased What did u write?

I cant remember exactly what I wrote. Something like: Increase in angle theta would result in a lower horizontal force because Tcos(theta) would reduce hence low/no resultant force horizontally on the pole so little/no acceleration of the pole horizontally... And I wrote some jack sh*t about the vertical getting larger as angle increases Tsin(theta) ..

Well i was also doing that intially measured the horz. Distance and got 3.2cm then i measured the vertical dist. of the image and the ruler showed something around 7cm but the ques stated the the dist to be around 0.44m ..which obivously dont match..so yeah than i scalecd the horz. distance according to the ratio from the image..
Use scale eg 1cm=0.1m So 4 willbe 0.4 mm like that !
For steel I said steel has high tensile strength..etc. Is that okay? I was so freaked out during the exam. I was so stressed and all my classmates found the paper hard. I'm so scared, I'm so scared of a B
