Question

Two unlike parallel force of 10 N and 30 N acts
at the ends of the rod 150 mm long. Find the
magnitude and position of resultant force.​

Answer 1

Answer:

Explanation:

Consider the point at which resultant of the forces will act, is 'x' m from the point A.

Thus the point is (1.5 - x) m far from point B.

Thus, using the formula Torque = Distance x Force acting

20x=30(1.5−x)

or,2x=4.5−3x

or,5x=4.5

or, x=0.9mor90cm

Thus the resultant point will be 0.9 m or 90 cm far from point A
