Question

As shown, an L-shaped bar is supported by a pin at joint A. The bar's dimensions are a = 700mm and b = 390mm , and the bar is subjected to a force with magnitude F = 5.45kN at joint B. Ignoring the bar's weight, find the actual orientation of the applied force. What is the value of the angle ??

Explanation / Answer

It will be such that the moment will be zero about the pin joint
F*cos theta *b = F*sintheta*b = tan theta = b/a = theta = 29.12 degress
