5-point star resultant force question

AI Thread Summary
To solve the 5-point star resultant force question, start by determining the angles between the forces, which are equal due to the star's uniformity. The angles can be calculated using the total sum of angles in a circle, divided by the number of forces. With one known force acting straight down at 70N, the horizontal and vertical components of the other forces can be derived from these angles. Understanding the relationship between the forces and the angles with respect to the positive x-axis is crucial for accurate calculations. This approach will facilitate the conversion of each force into its components.

Any help on where I start with this question. Need to convert each force into its horizontal and vertical components, but don't know any angles apart from the 70N force acting straight down.

The lines of the forces connect the vertices of a regular pentagon to the centre. What angle do they enclose with each other? What are their angles with respect to the positive x axis?

Surely you can figure out the angles. The star is uniform, so the angle is the same between any two adjacent forces. And you know what the sum of all the angles is.
 
Thanks for the help.
 

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...
