Equilibrium force problem torque

AI Thread Summary
To solve the equilibrium force problem involving a beam supported at two points, one must account for the beam's weight and the additional weight placed on it. The beam is 8 meters long, weighs 6 kg, and has a weight positioned 2 meters from the right support. The correct approach involves drawing a free body diagram (FBD) to identify all forces acting on the beam, including the normal forces at each support. The calculations should ensure that the sum of torques and forces equals zero for equilibrium. Proper setup and understanding of these principles will lead to accurate calculations of the forces on each support.

there is a beam 8 meters long that is supported by two supports. the beam weighs 6kg and a weight is put 2m from the support on the right. what is the force on each of the supports?

could someone please explain how to do this, my solutions turned out to be 49 and 88, when i believe it should be 45 and 92. i know torques have to be involved but i did it without

How did you get those answers?
 
there is the force weight from the beam, weight from the block, and normal on each support. can anyone tell me how to set it up, that's all i really need.

First, draw a FBD and label all of the forces acting on the beam.

Include the distance from one of the end supports to mass and the other end support.

Second, think about the requirements for equilibrium.

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}...
