1. The problem statement, all variables and given/known data In the attachment 2. Relevant equations F = ma F = mg Ffriction < μ*N 3. Attempt at a Solution Okay so I know that the weight is weighing down with a gravitational force of ~750 N. Similarly, I know that the two forces on the wall will both provide frictional forces pointing up with a magnitude equal to μ*F. So I set (mg)/2 = μ*F and got something along the lines of 910 Newtons. I'm convinced this is correct because I can see no other way to do it. The book's answer is 52 Newtons which doesn't make sense because you'd have a combined force of 104 Newtons holding up a gravitational force of ~750 Newtons. I'm looking for someone to either confirm that I'm doing it correct or point out what I'm doing wrong. Thanks.
