40 Chapter 3 Modeling Electrical and Electromechanical Systems Equation (3.70) can be simplified by multiplying both sides by R₁+R₂ €o(R₁ + R₂ + KR₁) = -KR₂ein (1) Finally, the output voltage is ²0 -KR₂ R₁ + R₂ + KR₁ €o = €(1) -R₂ R₁ (3.71) Because the gain K is extremely large, we can take the limit of Eq. (3.72) as K→ ∞o to obtain the output voltage relationship for an ideal op-amp circuit (3.72) (3.73)

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

Learning Goal: To understand how to use the relative position and velocity equations to find the linear and angular velocity of members in an assembly. A piston is driven by a crankshaft as shown. The crank arm (member AB) has a length of r₁=0.55 in and the connecting rod (member BC) has a length of r2 = 4.25 in. The crankshaft rotates in the counterclockwise or positive direction.

can you please do the quadratic interpolaton on paper so I can see how you did it
I have been working on this Solid Mech problem for a while and have gottem nowhere we are supposed to be finding the modulus of elasticity for a set of data (attached). I have made an excel sheet from this to finda stress strain graph. I understand how the modulus of elasticity is (E = (delta stress)/(delta strain)) but I cannot find the propotional limit that I need to find delta stress and delta strain
