Finding V(out) of Operational Amplifier

AI Thread Summary
To find the output voltage (V(out)) of the operational amplifier powered by ±20V DC, the discussion emphasizes using the given resistances and battery values. The known voltages V1 and V3 can be easily identified, leaving V0, V2, and the output currents i1 and i2 as unknowns. Participants suggest writing equations that sum the currents to zero at each node (V0 through V3), resulting in four equations for the four unknowns. Utilizing math software to solve these equations is recommended for efficiency. The approach focuses on systematic analysis to determine the output voltage accurately.

Hint #1: V1 and V3 are obvious by inspection.

That leaves V0, V2, i1 and i2 as unknowns where i1 and i2 are the op amp output currents.

Write equations summing currents to zero at V0 thru V3. That's 4 equations and 4 unknowns. Stick the equations into your math software.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
