Correct me if i am wrong: The ball would spin (rotational>linear) if friction>required OR slid (linear>rotational) if friction<required. Finally, the ball would pure roll (vcm=rw) if friction=required.
friction is the factor that you'll need to consider.
so, the equation would be:
ug=v^2/r, where u is the coefficient of static friction between the track and tires. If the track is at an angle, the equation will be slightly different.
In general, the critical angle, or the angle at which an object is about to topple is the angle between the vertical/horizontal and the line passing through the centre of mass and the edge over which the object is about to topple.
I think you misunderstood me. A typical example is a ball rolling down an igloo from the top. The friction changes as it goes along the surface. So, when the ball starts sliding, is the friction less than or greater than required friction for rolling?
How does friction affect the type of rolling motion of an object. For instance, does having more friction than the required friction for rolling cause the object to spin?
im just saying they both are related in the way we solve them. This question's answer is certain but not the first one. I posted the question so that you get the idea of it.
as per my prof's explanation, we are allowed to assume any sensible motion for the masses. so here, both equations assume m2 and m3 are moving up while m1 is moving down. The general method to solve these equations, as per my prof's suggestion, is to find the displacement. So, for the following...
Homework Statement
Find the relationship of acceleration between the masses, m1, m2 and m3 where m1>m2>m3.
The question has a free pulley in the left attached to mass m1. then goes through a fixed pulley , through a free pulley that is attached to m2 and then through a fixed pulley, with the...
Aspirator design?
I need to remove dust from sesame seeds so i decided to make a zigzag aspirator. I have searched the net and found a bigger version but I need to make a smaller version. I have attached the picture. I need to know the inner layout of the top part (aspirator) A small sketch...
