    A question like this could because it is built off of the principles that you have learnt in M1. The topics it includes is incline planes, resolving forces, pulleys and moments.

    Thanks!

    Can I not do -p + 2r + p = 2r but that's wrong? :/

    I mean why for OQ can I not do like OB + BQ?
