AI Thread Summary
The problem involves calculating the radial force exerted on a bar connected to a long beam, with an initial force of 100 N applied. The user attempted to find the radial component of this force using trigonometry, resulting in a calculation of 60 N at one point and 36 N at another. However, the user acknowledges that these calculations do not yield the correct answer, indicating a misunderstanding in their approach. The discussion seeks clarification on the correct method to determine the net force on the bar. Accurate calculations are essential for resolving the issue effectively.

I've attached a problem, which I have tried to solve unsuccesfully.
My attempt at a solution:
I would say that the force you exert on the bar is the radial component of your force with respect to the long beam. And using trigonometry to find the angle in the triangle you get:
Frad = 3/5*100N = 60N
And I then do that again at point B because I only want the horizontal part of the radial force. So I then get:
F=36N
And the bar must be pressing against the hinge with that same force.. But that's not the correct answer as far as I know - actually far from it.. So I am clearly thinking wrong some place :( help me

The force exerted on the bar is given: F = 100 N. What's the net force on the bar?
 

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}...
