Find Tension of Rope in Two Blocks System: 5kg, 7kg, 4kg, 200N

AI Thread Summary
To find the tension in a system of two blocks (5kg and 7kg) connected by a uniform rope (4kg) with an upward force of 200N, start by applying Newton's second law (F = ma) to each block. Create separate free body diagrams for each mass to analyze the forces acting on them, including the tension in the rope. Recognize that all components of the system will accelerate at the same rate due to their connection. The tension will vary at different points in the rope, so calculate it at the top, midpoint, and bottom using the respective forces acting on each segment. Understanding the distribution of forces is crucial for accurate tension calculations.

Homework Statement


two blocks of masses 5kg and 7kg are connected by uniform rope of mass 4kg.an upward force Force=200N is applied on the system .How to find the tension at top, lower and midpoint of the rope

Homework Equations


(take g=10m/second square).I only know this.Please tell me the formula to calculate the tension at top,lower and midpoint of the rope.

You've got a start on your force diagram. It looks good as far as you've gone. Finish it. First hint: F = ma.
 
As Bystander writes, you need to show all the forces in the diagram. However, I would suggest you do this with separate free body diagrams for each part on which a force of interest acts directly. How many such components are there?

By the way, please use thread titles which give some guidance as to the topic. It will help you get timely answers.
 
The trick is to realize that everything must accelerate at the same rate because they are tied together.
 

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'

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...
