Cam Follower Reaction Forces in Accelerating Roller Cart

AI Thread Summary
The discussion focuses on calculating the reaction forces on cam rollers of a roller cart accelerating at 20 m/s². The cam followers have diameters of 25mm and 32mm, with a mass of 4kg. An initial calculation suggests 222 N acting on the smaller roller, but there is uncertainty about the force on the larger roller and the application point of the acceleration force. Participants are encouraged to identify all relevant forces and equations to clarify the problem. The conversation highlights the need for collaborative problem-solving in physics.

Homework Statement



Cam followers are 25mm and 32mm in diameter. Mass is 4kg. Determine the reaction forces on all of the cam rollers when cart accelerates to the right at 20 m/s^2

Homework Equations





The Attempt at a Solution


(4kg)(20m/s^2)(.05m)/(.018m) = 222 N on small roller to the right? Is there an equal but opposite force on the large roller too?

Where is the force applied that is causing the acceleration?
 
assume it is applied 25mm directly below the C.G. (inline with C.G./centered between small rollers)

So I guess there is no one here who knows the answer!??
 
Sorry for the delay - for some reason my standard search didn't pick up your earlier reply.
You suggest (4kg)(20m/s^2)(.05m)/(.018m). I think it's only half that.
List all the forces you believe will operate and write down any equations relating them that you can think of.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
