Equilibrium normal reaction force problem

AI Thread Summary
The discussion revolves around a physics problem involving equilibrium and normal reaction forces. A user expresses difficulty in solving the problem despite attempting to set up free body diagrams (FBD) and equations. They derive two conflicting values for tension (T) using the equations Tsin30° - 752N = 0 and 344N - Tcos30° = 0. The user is reminded to identify all forces acting on the ball and balance them, which hints at the importance of recognizing the normal reaction force. Ultimately, the user acknowledges a mistake in their approach, indicating a need for a clearer understanding of the forces involved.

The Attempt at a Solution


This should be easy, but I'm tired and just can't do it. If anyone can point me in the right direction that'd be great. I tried making a FBD, and had the equations:
Tsin30^{\circ} - 752N = 0
344N - Tcos30^{\circ} = 0

But, that then gives me two different answers for T. So I'm lost.

note: the question asks you about the normal reaction force, doesn't that give u a hint?
 
Is the answer 752N?
 
first identify all forces acting on the ball, draw a force diagram and then balance them.
there should be 4 different forces acting on the ball
 
Haha, well that means I got the question wrong. Damn.

Tsin30^{\circ} - 752N = 0
344N - Tcos30^{\circ} = 0

?
 

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}...
