Force on three Bolts holding up a Jet Engine

AI Thread Summary
The discussion centers on calculating the force on three bolts supporting a 1400-kg jet engine. The initial assumption was that the force on the bolts would be 0 Newtons since they are not moving, which is incorrect. The correct interpretation involves calculating the tension on each bolt, as they support the weight of the engine. Each bolt would therefore bear a load of approximately 4,600 Newtons when the plane is stationary. Understanding the distinction between net force and tension is crucial for solving this problem accurately.

Homework Statement
A 1400-kg jet engine is fastened to the fuselage of a passenger jet by just three bolts (this is the usual practice). Assume that each bolt supports one-third of the load. Calculate the force on each bolt as the plane waits in line for clearance to take off.
Relevant Equations
F=ma
y=y0+v0t+(at^2/2)
My solution was that there would be a force of 0 Newtons on the bolt as the bolt is not moving. But this answer is wrong. Where am I going wrong?

I doubt they mean to ask for the net force, though I agree that is a strictly correct interpretation. Rather, they want the tension on each bolt.

Ohhhh ok. Thank you so much!

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...

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}...
