Acceleration and tension of block on a table

AI Thread Summary
The discussion focuses on analyzing the forces acting on two blocks connected by a pulley, one weighing 466 N on the table and the other weighing 205 N hanging off the edge. It emphasizes the importance of ignoring friction and treating the pulley as massless. Participants are encouraged to identify the forces acting on each block and derive equations based on these forces. The relationship between the blocks' accelerations is also highlighted, indicating that they will share the same acceleration due to their connection. Understanding the forces and applying the correct equations is crucial for solving the problem effectively.

In the drawing, the weight of the block on the table is 466 N and that of the hanging block is 205 N. Ignore all frictional effects, and assuming the pulley to be massless.

the drawing is of two blocks, one on the table, one hanging off. connected by a pulley.

the question asks for acceleration and tension

OK, but please show some work. What are the forces acting on the 205 N mass?

What forces are acting on the 466 N mass?

What can be said about the acceleration of the masses?

Also do you know how to draw forces acting upon an object? If so try doing that first and get your equations from there.
 

Thread 'Errors and significant figures'

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'

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...
