How to Solve for Unknown Forces in Equilibrium Truss Problems?

AI Thread Summary
To solve for unknown forces in equilibrium truss problems, applying equilibrium equations is essential. The user calculates the force at point C (Fce) but seeks clarification on how to derive forces Fbe and Fbd. The calculated values are Fbd = 95.6 kip, Fbe = 41.1 kip, and Fce = 58.4375 kip. A participant explains that "kip" refers to a kilo-pound, which is a unit of force. Understanding these calculations and units is crucial for resolving truss problems effectively.

I am stuck trying to see how to apply the equilibrium equations. I take the moment about point b and get Fce. I need Fbe, and Fbd.

Fbd = 95.6 kip
Fbe = 41.1 kip
Fce = 58.4375 kip

These are the answers. I don't know how they got Fbd and Fbe, any clues??

what units are you working in. I've never heard of 'kip' being used. Ca you tell me what that is.

It's a kilo-pound.
 

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}...
