Answer 1

Answer:

j

Explanation:

Answer 2

Explanation:

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

Rx=ΣFxRx=ΣFx

Ry=ΣFyRy=ΣFy

R=Rx2+Ry2−−−−−−−−√R=Rx2+Ry2

The inclination from the horizontal is defined by

tanθx=RyRxtan⁡θx=RyRx

The position of the resultant can be determined according to the principle of moments.

MR=ΣMOMR=ΣMO

Rd=MRRd=MR

Ryix=MRRyix=MR

Rxiy=MRRxiy=MR

Where,

Fx = component of forces in the x-direction

Fy = component of forces in the y-direction

Rx = component of thew resultant in x-direction

Ry = component of thew resultant in y-direction

R = magnitude of the resultant

θx = angle made by a force from the x-axis

MO = moment of forces about any point O

d = moment arm

MR = moment at a point due to resultant force

ix = x-intercept of the resultant R

iy = y-intercept of the resultant R
