Question

Twelve forces each of 10N act on a
body simultaneously. If each force
makes an angle of 30° with other,
their resultant is
(A) 10 N
(B) 120 N
(C) 60N
(D) Zero​

Answer 1

Answer:

Resultant of Concurrent Force System

Rx=ΣFx=Fx1+Fx2+Fx3+... The x-component of the resultant is equal to the summation of forces in the x-direction.

Ry=ΣFy=Fx1+Fx2+Fx3+... The y-component of the resultant is equal to the summation of forces in the y-direction.

Rz=ΣFz=Fx1+Fx2+Fx3+...
