Jwill said:I understand that I need to find acceleration but I don't understand what to do about the acceleration of blocks being different. I come up with 3.0769m/s^2 for A and 4m/s^2 for B. How do I use this to find the tension?
Jwill said:They are acting in the same direction. So would that mean 24N - 16N = 8N as the net force?
Jwill said:I guess there's no reason to subtract... the sum would be 40 and the mass of the system is 11.2kg... so that'd make the acceleration 3.57m/s^2.
Jwill said:It would be the one lagging behind right? The thing that kind of confuses me is the outcome is 18.564N and I'm supprised that even though they're both moving in the same direction with forces how there is still so much tension between the two blocks. Thank you for your help by the way.

You need to take into acount that Tension is not the only force acting on each of these blocks.Jwill said:I used f=ma ... 5.6 * 3.57m/s^2 = 18.564N. Is that not the correct formula for tension? or did i apply it incorrectly?
Jwill said:Still have no idea what to do... shouldn't be that hard of a problem.. just missing something
Jwill said:16Ni and gravity i guess
Jwill said:And that would add to 16N force right?
Jwill said:So that makes me think 16N + T = 3.57(5.2) which isn't right i don't think is it?
Jwill said:Yes A is the lagging mass... for A i used T = 3.57(5.2) - 16
Jwill said:So would that make the tension on the rope be 5.144N by adding the magnitudes?
Jwill said:So would that make the tension on the rope be 5.144N by adding the magnitudes?
Jwill said:Why does T = 3.57(5.2) - 16 for A
and T = 3.57(6) - 24 for B
produce different results?
Jwill said:Nevermind, it was because 3.57 is rounded... thank you very much... you've helped me better understand tension
To calculate the tension in a connecting string of two blocks, you need to consider the weight of the blocks, the angle of the string, and the acceleration of the blocks. You can use the formula T = (m1 + m2) * g * cosθ, where T is the tension, m1 and m2 are the masses of the blocks, g is the acceleration due to gravity, and θ is the angle of the string.
Calculating tension in a connecting string of two blocks is important in understanding the forces acting on the blocks and the string. It can help determine if the string is strong enough to support the weight of the blocks and if the blocks will move or remain stationary.
No, the tension in a connecting string of two blocks cannot be negative. Tension is a force and forces can only be positive. However, the direction of the tension can be positive or negative depending on the direction of the acceleration of the blocks.
The angle of the string affects the tension in a connecting string of two blocks because it changes the direction of the force. As the angle increases, the tension decreases and vice versa. This is because the weight of the blocks is distributed between the vertical and horizontal components of the tension.
Calculating tension in a connecting string of two blocks is important in many real-life situations such as construction, rock climbing, and engineering. It is used to determine the strength of ropes, cables, and other materials used to support heavy objects. It is also used in designing pulley systems and elevators.
