What If the velocity of particle moving in a circular orbit has increased , would the particle be no longer in circular orbit or it would go in an orbit with bigger radius?

and what is function of theta

The angle is 48 as sir walter said , and I'm trying to reach it and get that answer

But torque from the normal force from the block should be zero as it acts at pivot point

So normal force from the block directed radially or in the x direction

And does normal force from the block does torque?I don't understand why we need opposite torque

So both normal force from ground and the other one from the block does centrepetal acceleration in addition to gravity?

It slided also but only when it lied at the ground. But , can a force which is applied from the pivot point make a radial acceleration?(i.e the normal force from the surface that touches the pivot point , this question might be a littel far from the main one but it'll help me through this...

I pushed the ruler a bit and it started to fall then it's gone away from the block i put behind it , and slided until it lied at the surface. Yes v is com velocity. This problem is more trickier for me , I even tried to search about it but i didn't find anything helpful.All I'm seeking for are...

I didn't write nlsin(x)/2 in the equations. Yes , i did It wouldn't slide if he didn't put the timer. And it slided when i did it So Mv^2/l=mgcos(x) ?

I can't understand what you mean, can you explain further? Yes , I have made that experiment twice. Only thing still confusing me is what makes the centrepetal force to the center of the mass .

Describing normal force from the floor. Maybe, ruler wouldn't slide , correct?

It should point to the center of the circle that com moves around , but the normal force here has a component that point outward , so it's decreasing the centrepetal force , so it should be in the equation . I think he used his timer to apply force to the ruler

Okay , but I wonder if the normal force is making centripetal force component. that is what confused me

Yes , the same There are two problems in that video I 'm trying to solve the second one starting from minute 8:04
