Professor Hanson, thank you so much for this incredible review of another Friction Wedge problem and many other significant exam problems in Statics. I hope that all students in Statics do very well on future exams.

Wonderful Statics lessons!! really taking the time to explain the problems along with a good sense of humor :))

[jkgaming]

I have this exact problem on my homework! This is clutch.

[Peter_]

I like how he calls impeding motion "fun friction".

Thank u sir this is really helpful in my incoming board exams

I guess in this specific problem we don't take into account the masses of the blocks? (mg in the y direction)

Why don't we take force due to gravity in Free Body Diagram ??

Where does the 45 degree angle come from? The book has 20 degrees.

Hello Jeff, could you add an example of Solids where distributed loads are at an inclined plane instead of horizontal or vertical?
How to do a SF AND BM Diagram for this case?

[sethmcdaniel]

Using the 20 degree angle from the book I got P = 3340 N or 3.34 kN. Please like or reply if you got the same answer!

[kylabiancatuano]

hi! may I know why the weight of block B wasn't considered?

[abrahamdebasu]

11:45 that what I always said to m professor, when he starts explain so badly 😂

[tatjoni]

That's all well and good, but the answer isn't P = 9, 87 kN. The answer should be P > 9, 87 kN.
