Forces, F1, F2, F3, F4 and F5, are applied on point A, B, C, D and E respectively.
The door moves with same speed every time.
Suppose the forces are all perpendicular to the door, using the information below,
Point A B C D E Force / N F1 =
20.00 F2 =
22.86 F3 =
22.86 F4 =
32 F5 =
40 Distance from the hinge / cm 80 70 60 50 40
a) Find the torque produced by the forces at their corresponding points
b) Explain the relationship between the values found in part a.
I already have idea on how to do part a,
so, please mainly focus on part b.
THX a lot !!!
更新1:
Also, assume that there is no friction, air resistance....
更新2:
THX!!!

Re 天同 Yes, you're right, it should be 26.67

Re輝輝 For part b, in my view, you're just repeating what the question stated Is there a more in-depth explanation/formula/theory that can show "torque at different points is the same"? OR, what you have said is something like "principle"/"axiom" ?
更新5:
Just, I don't understand. Nevertheless, THX a lot!
