in Question 15, how do we arrive at

Centre of mass distance from origin = [x.sin(alpha)/alpha ] ?

Is the derivation of the distance of the strip from origin possible or we just have to learn it that way ?

examples 14 and 15 to be precise. anyways Roshnain, do you have notes of chapter 14 and virtual motion? I am going to attempt them, for virtual motion I might get help from key but the key does not have solutions of chapter 14.
regards

I have a book named Mechanics by Iqbal Haider Bhatti. I had given it a cursory look -

Does the course for Peshawar university also contain the same topics and questions of Mechanics? If thats the case i can get hold of notes from somewhere in Peshawar. I have not dug deep into this subject, but the horrendous length of the solutions and the intricate integrals are sufficient revelation upon me that I should start working on it .

I had given a look to the virtual work solutions - my intuition is that i can solve them but the fun part is - i am still to understand what exactly this virtual work thing is ? . for chapter 14, I have not even peeked at what lies in there .

I will start working on Mechanics and then we can share solutions and suggestions. What i ve partially covered is the tensor section and have been on and off at studies thereafter.

Is it OK to start Mehchanics from chapter 2 or you have a better suggestion?

7,8,9,10,12,5,2,3,4,6,14

and i had earlier told you as well to leave 20 marks tensors alone
