L6.7 Friction || Concept of Wedge Friction ,Problem #1| Engineering Mechanics| First year students

[@anantsharma7496]

great explanation sir

[@shangfeng3997]

at 7:42 why dont we consider weight of larger block on wedge?

[@mritunjayrajbhar9567]

Thank you so much sir

[@moditpathak6323]

Sir, i couldn't understand the direction of friction in slant surface...

[@ashishpurohit9138]

Pls specify time and instance

siri have a doubt...............................................sir you have not considered weight of second block????

[@aadityachaturvedi3937]

Sir p value is -133.78N

[@amitsinghyadav7843]

yes

[@G_D123]

How we will get to know about the direction of N2

[@ashishpurohit9138]

Can you please specify time instance...

[@ashishpurohit9138]

If you are talking about normal reaction between two wedge surfaces..the normal reaction always towards the surface and normal to the surface

[@G_D123]

@@ashishpurohit9138can the N2 be moving away from the wedge in ur case it is towards the wedge means towards M(the body to. Be lifted)

@@G_D123N2 is a reaction between common surface of top and lower bodies..means lower body experiencing it from top body thus act towards CG of lower body.. similarly same reaction acting from lower body to top body...in FBD a Reactions always act toward the CG of vody
