    Formula Tension
AI Thread Summary
The discussion revolves around understanding the concept of tension in physics, particularly in a scenario involving penguins being pulled on frictionless ice. Participants clarify that tension can be understood as a force, using the formula F = m*a to relate mass and acceleration. There is also a query regarding the calculation of the force exerted by a rope on a bucket, where the normal force and gravitational force need to be considered. The conversation highlights confusion surrounding these concepts, indicating a need for clearer explanations of tension and related forces. Overall, the thread emphasizes the importance of grasping the fundamental principles of tension in physics.

Figure 5-48 shows four penguins that are being playfully pulled along very slippery (frictionless) ice by a curator. The masses of three penguins and the tension in two of the cords are m1 = 12 kg, m3 = 16 kg, m4 = 23 kg, T2 = 112 N, and T4 = 212 N. Find the penguin mass m2 that is not given.

I really cannot find the formula for tension at all and also i don't understand the tension concept at all. So please can somebody help me please.

Thanks

Tension is just Force.

Use F = m*a
 


Hello everyone,

I'm having a doubt with my Physics homework. I need somebody's help!

To find the force exerted by the rope on a bucket of water that is raised from a well I have to find the normal force (m*A upward accelaration of the bucket) and that is the one or I should find the force of gravity (m*G) and substracted from the normal force and that is the force exerted by the rope?

Thankss
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
