Hi, I once considered myself enough to be decent enough to solve some problems but lately I'm thinking to revisit and start solving problems again. I would like to know whether there is a book good which has problems (starting from basic to tough ones) for practicing free body diagrams. The book should also have ample illustrations of FBD's. My approach is to getting better at drawing FBD's is that I would first look at worked out problems and then go to unsolved ones. Also are there any books, strategies or resources which can improve problem solving skills in general? I would be thankful if you can point me to good books or resources having these characteristics. Any other advice to help getting better at drawing FBD's is also welcome. Thanks again.
