Calculating Speed Along Sides of Right Angle at Intersection with Ruler

AI Thread Summary
The discussion revolves around a physics problem involving a ruler moving perpendicularly to the bisector of a right angle at a speed of 10 cm/sec. Participants clarify that the bisectrix refers to the same concept as the bisector, with the term being gendered in mathematical terminology. There is confusion regarding the physical setup, particularly whether the right angle is aligned with the edges of the paper. The main focus is on understanding the relationship between the ruler's movement and the points of intersection along the sides of the angle. The conversation highlights the importance of visualizing the scenario to solve the problem effectively.

Homework Statement


A right-angle is drawn on a sheet of paper. A ruler , which always remains perpendicular to the bisectrix of this angle moves over the paper with a speed 10cm/sec. The ends of the ruler intersect the sides of the angle. What are the speeds along the sides of the angle of their points of intersection with the ruler?


Homework Equations







The Attempt at a Solution


I'm not asking anyone to give me a solutions I am just having difficulty picturing the physical scenario described in the question
1) Am I right to assume it means a right angle with legs parallel to the sides of the paper?
2) I don't understand what bisectrix means if not bisector and if so then how is the ruler perpendicular to the bisectrix and what is the bisectrix?

hi teddyayalew! :smile:

bisector and bisectrix are the same, bisectrix is the female version, and apparently lines are feminine!
 

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...
