Three forces are exerted on the lever of Figure 12.7. Forces \(\vec{F}_{1}\) and \(\vec{F}_{3}\) are equal in magnitude, and the magnitude of \(\vec{F}_{2}\) is half as great. Force \(\vec{F}_{1}\) is horizontal, \(\vec{F}_{2}\) and \(\vec{F}_{3}\) are vertical, and the lever makes an angle of \(45^{\circ}\) with the horizontal. Do these forces cause the lever to rotate about the pivot? If so, in which direction?
