AI Thread Summary
To solve a pulley and distributed load problem for an engineering exam, it's essential to understand the line of action of the weights involved. The weight of the two right-angled laminae acts through their centers of mass, which are not necessarily at their midpoints. A clear diagram and step-by-step calculations are crucial for demonstrating the solution. Engaging with others for insights and verification can enhance understanding. Properly showing your work will be vital for exam success.

You have to show your work.

I think the line of action of weight of the two right angled lamina will through their center of mass which are not midway.
 
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}...
