AI Thread Summary
To find the tension in the string for an object of mass M moving in a horizontal circle with radius R at speed v, consider the forces acting on the object. The tension T can be resolved into horizontal and vertical components, where the horizontal component provides the necessary centripetal force and the vertical component balances the weight of the object. Using the equations for centripetal acceleration and gravitational force, the relationship can be established. A vector diagram can help visualize the components of tension. Ultimately, the tension T can be expressed in terms of M, v, R, and g.

Homework Statement


An object with mass M is whirled with constant speed v on the end of a string in a horizontal circle of radius R. the string makes an angle, (theta) with the horizontal. The tension of the string is T.

Find the tension of the string in terms of any of the given variables and g.

The Attempt at a Solution


Sorry i have no clue :(
 
Physics news on Phys.org
Force centripetal acceleration = (mv^2)/r (x-axis)
Force gravity = ma (-y-axis)
Draw a vector diagram
T = "hypotenuse"
 

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...
