AI Thread Summary
The tension in the wire used in braces must be calculated to ensure a net force of 0.7806 N on the tooth, with an angle of 156.5° between the forces. A free body diagram is essential for visualizing the forces acting on the tooth, making the problem easier to solve. Participants suggest drawing a top view and focusing on a single tooth to clarify the forces involved. The provided link offers a visual reference for understanding the wire's configuration. Properly analyzing the forces will lead to the correct tension calculation needed for effective orthodontic treatment.

Homework Statement



What should be the tension in the wire used in teeth braces be, given that the net force exerted on the tooth has to be 0.7806 N? The angle between the two forces is 156.5°.

Homework Equations



I think we may have to find the centre of mass


The Attempt at a Solution



I really am clueless as to how to approach this.

You need to draw a picture (the free body diagram for the tooth). After that, it's much easier.

Look at this picture (for instance): http://www.drmehan.com/inovationclear%20(Small).jpg

Draw the top view and zoom in on a single tooth. The angle between the left and right sections of wire is given to you.

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
