Problem 260
The effect of a certain non-concurrent force system is defined by the following data: ΣFx = +90 kN, ΣFy = -60 kN, and ΣMO = 360 kN·m counterclockwise. Determine the point at which the resultant intersects the x-axis.
The resultant of non-concurrent force system is defined according to magnitude, inclination, and position.
The magnitude of the resultant can be found as follows
$R_y = \Sigma F_y$
$R = \sqrt{{R_x}^2 + {R_y}^2}$
Problem 233
In Fig. P-231, a force P intersects the X axis at 4 ft to the right of O. If its moment about A is 170 ft·lb counterclockwise and its moment about B is 40 ft·lb clockwise, determine its y intercept.
