Hi I am pretty confused on how my book is doing the calculus of electric fields. Basically I don't understand how their equation makes any sense (The integral equations on the second page). How does the indefinite integral become a definite integral? Is this a true equality or is it supposed to...

Hi everyone, I actually found out how to do this problem. Given the fact that everything is in equilibrium I can cut the "V" in half and look at each side using torque. Then I can solve for Fbar without getting a zero for an answer. Lol mastering physics...

Ok, Let L = length T = tension of each wire Fbar = force exerted by bar Well what I have so far is: Net torque about hinge = Tsin(153.5)L - Fbar * sin(63.5)L/2 - Tsin(153.5)L + L/2*Fbar*sin(63.5) = 0 And I get a zero each time I try to solve for Fbar

Homework Statement Two identical, uniform beams weighing 260 N each are connected at one end by a frictionless hinge. A light horizontal crossbar attached at the midpoints of the beams maintains an angle of 53.0 ∘ between the beams. The beams are suspended from the ceiling by vertical wires...
