AI Thread Summary
The optimal angle for maximum torque in a balancing torque problem is 90°, as this configuration provides the highest torque. When the angle between the rod and the rope is 65°, using sin(65°) for the rope tension component normal to the rod is appropriate. There was confusion regarding the use of sin(25°), but it was clarified that sin(65°) should be used instead. The discussion emphasizes the importance of correctly identifying the angle to calculate torque effectively. Understanding these angles is crucial for achieving maximum torque in practical applications.

If the angle between rod and rope is 65°, then using sin (65°) for the component of rope tension normal to the rod is correct.

Edit: Sorry about that, I was thinking of cos (25°) which would yield the same as sin (65°).

Wait so in the above equation using sin 25 would be the correct one?
 
NO, use r ft sin 65 , like you did.

if the angle between the rod and the wire had been 90,
it would have provided maximum torque possible (not zero).
 

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}...
