- A 20-N horizontal force is applied perpendicular to
the handle of the socket wrench. Determine the magnitude
and the coordinate direction angles of the moment created
by this force about point O. Get the book: amzn.to/2h3hcFq
You are honestly the greatest. You are a true bro for doing this work, it really helps a lot.
He really is

Small error at 6:00
0.075 x -19.3 = -1.45
not -1.47
Very helpful video though. Thank you!
God bless you.
Thanks.
could you do it again but this time at point B which is the head of the socket wrench where the z-axis is
bro you do it yourself tf?
Dude how do u know the angle for force is 15 degree?
It's a given in the problem
draw the force vector. it is angled toward the y axis. put the x axis and y axis on its tip and tail. by inspection the 15 degrees goes between the 20N force and the x axis which means the force is angled 75 degrees to the y axis. from this you know the x axis is adjacent to the 15 degree angle and thats why its -20cos15i + 20sin15j. pretty much since it is perpendicular you are drawing the same triangle in the diagram but shifted for the force
I know it is very basic stuff, but could you make a video explaining how you know that the angle is the same between the two components (15*), please reply if you do make it. Thank you.

This does not make since. The 15 degree angle is between the Y axis and the ratchet handle. Not the force vector and the X axis. Please re-explain this! This part has me sooooo confused.
@@johnbowman9734 9 months after you commented this another student(me) is confused about the same thing lol
@@matthewpark4294 still do not get it sigh
First of all I appreciate you and thanks you for making these videos.But unfortunately Chapter 5 and after that is not posted . I recommend you to make new videos of chapter 5 full videos and also other chapters Thank you

For videos on rigid body supports 😊
Will you be my dad?
HAHAHHAHA
