Statics: Exam 3 Review Problem 7, Friction Wedge Example

[@georgesadler7830]

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 :))

Keep pumpin the problems Keeps my brain refreshed i love em Love you prof

[@Peter_1986]

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

[@RK-tx5xb]

Great example professor.

[@EngrJapzML]

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

[@laurawoo9752]

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

[@sarthakmanchanda8226]

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

[@corneliuscornwall2036]

youre the best!!!

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

[@RK-tx5xb]

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?

[@Berzerkgear]

the best !

[@sethmcdaniel5654]

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!

[@kylabiancatuano8397]

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

[@1234jhanson]

A lot of problems state that the weight of the blocks are negligible. Some problems do consider the weight of the blocks. Always carefully read your problem.

[@kylabiancatuano8397]

@@1234jhanson got this, thank you so much! 😁

[@abrahamdebasu2751]

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.
