Cable Tension

AI Thread Summary

The discussion centers on calculating the tension in the cable used to airlift a 78.0 kg snowboarder by an 1800 kg helicopter at constant velocity. Key forces acting on the snowboarder include gravitational force and tension in the cable. Since the snowboarder is moving at constant velocity, the net force is zero, allowing the application of Newton's 2nd law to find the tension. The gravitational force acting on the snowboarder is calculated as 764.4 N (78.0 kg x 9.81 m/s²). Therefore, the tension in the cable equals the gravitational force, resulting in a tension of 764.4 N.

an 1800kg helicopter with a cable and harness is rescuing an injured snowboarder.
the harness and snowboarder have a mass of 78.0kg
what is the tension in the cable when the snowboarder is being flown to safety at constant velocity while hanging in the harness?

I am completely lost on this problem and cannot find a starting point

What forces are acting? (Draw a diagram.) Apply Newton's 2nd law.

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
