Start out by drawing a FBD (free body diagram), analyze each force and write the conditions of equilibrium.
Yes, now apply the equilibrium conditions, Fx=0 and Fy=0. Also break this Tn into cosines and sines that will make the job easier. I'm sorry but i got to go now. I hope that does the trick.
hey it is just the same type of problem same as wat we discussed instead of numbers just put those alphabets given u have any problems with it let me know
u got it?
no boss i did this wit my teacher and we didnt have the marking scheme and its wrong i dont get it
show me wat u got with the diagram
ohh we forgot about that the normal force acts acts 90 degrees to the surface
now i get it
u have to always remember that frictional fgorce opposes net motion where is the net motion dirested? u have got T componet+mg in the down direction while to balance this friction operates above
It is directed downwards.Which means i am going to add the T component acting downwards with the mg to get FN
wat is normal force? we discussed eearlier that it is perpendicular to the plane of contact otfd the two bodies just like the previous question
yes! 'that is a perfect free body diagram
dont forget to resolve Tn
Yep roger that :) it means my teacher has got serious rust for physics
