I have an account but I can't permanently log in. And I know that I'm using the correct password because it does momentarily log me in and shows the message "Thank you for logging in, Mr Rayon". However, it then sends me to a page where I am not logged in.
A book, which may be modelled as a particle of weight 8N rests in equilibrium on a desk top inclined at 28 degree to the horizontal. ind the frictional force acting on the book. he coefficients of friction between the book and the desk top is 0.6. Determine whether the equilibrium is limiting.
F= 8 sin 28x.6= 3.75 ( parallel)
R= 8 cos(28)= 4.5
Answer given is 3.76N and friction is not limiting. may I know why friction is not limiting? Please explain
It's too late for this comment for most users but the Physics and Chem sites are down until the owner comes back and resuscitates them. I don't recall if we have a Biology forum or if it was in the planning stages. But if we did that's down too. we're focusing on the Math site at the moment.
