Homework Statement
A wire OA connects the collar A and a reel located at O as shown in the picture. Knowing that the collar moves to the right at a constant speed v0, determine θ'' (the 2nd-order-derivative of θ) in term of v0, b and θ.

Hi,
You are right, standing or constant-velocity-motion has no net force
Force is applied to maintain the acceleration. And the constant-velocity-motion has no acceleration then the force applied to it is zero.
When you are pending to throw a body projectile, its velocity is zero. Hence to let...
I see. But you know, I've started studying in university and there're still a lot of things to know. I hope I can join and become an active member of the forum. Thanks :)
Dear tiny-tim,
I've known how to solve it. We resolve all the force into x and y component. And determine the conditions that the tension force on the rope is more than zero
The cables are tied at A and loaed as shown
Determine the range of values of P for which both cables remain taut !

I have an idea on the AC rope. Since the tension force T must not be zero on the horizontal line (or the line along AC)...
