Physics 15 Torque Fundamentals (5 of 13) How to Calculate a Torque (Method 2)

In this video I will show method 2 of 3 of calculating torque = (force) x (perpendicular distance).

Next video can be seen at:

Hello,
How would you conclude that the given angle theta is the same as the angle next to the pivot point?
+1:40

[Tugba.aydinn]

But the object tends to rotate in a clockwise direction isn’t torque suppose to be (-69) ?

[alandaleb]

I think you meant 69 N.m for the final result..
Very helpful videos. thank you so much Mr. Biezen

[stealthcatfood]

Thank you so much for doing these videos, so helpful

[منوعات-تف]

we used to calculate the torque using the cross product of f x r sin theta but you are using the cosine ! why

[haluushi]

Thanx helped a lot but a question why did you use cos and not sin cuz it's supposed to be cross and not dot when we use the torque we use cross not dot which leads to using sin not cos am I right or...? Cuz it says cross in my book

Sir i ask one question why not make d = L sin . because sin is also opposite÷hypotunius , how do you know this cos . The base & perpendicular, how do you know, ?hypotinius i can find easily .
