Engineering Distance is a problem -- find shear force and bending moment diagram

Click For Summary
The discussion focuses on calculating the distance between points F and O in relation to shear force and bending moment diagrams. Participants emphasize the importance of this distance for accurately determining the area of the shear force diagram, which is necessary for constructing the bending moment diagram. The conversation highlights the need to express shear force V as a function of x, leading to the calculation of V(x) at the specified point. The problem remains unresolved, indicating a need for further clarification on the calculations involved. Understanding these concepts is crucial for successfully completing the homework assignment.

This distance because of the we need area of the 2 part of shear force diagram to draw bending moment diagram
 
Start from A and write the shear ##V## in the beam as a function of ##x##. What does ##V(x)## equal at the point in question? Slove for ##x##.

Thread 'Full bridge circuit with inductor and resistor'

The above is the circuit i am calculating the inductor current. During the positive half of the sine input D1 and D3 are conducting so the circuit becomes My calculations are as below Are the above equations ok? When transitioning from +Ve cycle to -Ve sine wave does the above equations still applicable? During the negative cycle the diodes D2 and D4 are conducting and the current direction is going into the inductor same as when diodes D1 and D3 are conducting. According to me the same...
