    Determining the forces in three cables.

    So could you give me a rough outline of your method.

    Determining the forces in three cables.

    Homework Statement Homework EquationsThe Attempt at a Solution 1. I first found the angles each cable made with the pillar. 2. With these angles I found the components of the forces in the x and y direction. 3. So ∑Fx and ∑Fy were found. 4. Then using these values I equated...

    Direction of Current between nodes

    Its okay I have worked it out I just am unsure why the voltage drop over the 4 ohm resistor is from left to right.

    Direction of Current between nodes

    So how would I determine the direction of the voltage drop without knowing the direction of the current due to the passive sign convention.

    Direction of Current between nodes

    Say for example you had the following circuit. Since it is hard to determine which source will have a bigger influence on current I am unsure of how I would determine which way the current would flow between each node.

    Use the Node Voltage method to solve

    I got VC = 2.5 V

    Engineering Non Inverting Op-Amp Circuit Analysis

    Homework Statement For an input potential (Vin ) which is a 1V (peak) sinusoidal source. Calculate V1 and Vout Homework Equations - The laws for an op-amp - NVM The Attempt at a Solution Here is my attempt not sure if correct.

    Use the Node Voltage method to solve

    I figured Va = Vb + 15 and it worked!

    Use the Node Voltage method to solve

    Thanks I have now managed to solve this!

    Use the Node Voltage method to solve

    Simplified Circuit. This is what I have done. I think I have made a mistake somewhere. NOTE: VB is meant to be negative at end where = 76.67V

    Use the Node Voltage method to solve

    Actually I think I have it just wait.
