What about people who write songs? Many say the songs came quickly in their heads or they "heard" the lyrics or music..they usually say it's a Muse. What's the difference? These people get honored for their music, while others are called crazy. Even many Christian songs were written this way.(ex. "And I'll Rise Again" was written in less than 10 min..and it "came to him".) Please explain. (If you want to make fun or criticize etc..please go to the R&S site..they love to play that game. That's why I (and many others ) left it.

The reason I wanted to switch my major to mechanical engineering is because the undergraduate program in biomedical engineering taught me a bit of every subject: biology, engineering(mechanics, circuits......) but I didn't learn none of the subjects in depth. That is why I wanted to switch to mechanical engineering for graduate school to have an stronger engineering background to eventually work in the medical device field. I am just a concerned since I didn't take the undergraduate courses in mechanical engineering..& it seems to be a tuff major
Thank you in advance = )

A sled weighing 61.0 N is pulled horizontally across snow so that the coefficient of kinetic friction between sled and snow is 0.100. A penguin weighing 73.0 N rides on the sled, as in Fig. P4.76. If the coefficient of static friction between penguin and sled is 0.700, find the maximum horizontal force that can be exerted on the sled before the penguin begins to slide off.
