Question

16] Find resultant of forces when two like parallel forces of 40N and 70N which act at the ends of therod 40cm long. ​

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 (40 - x) m far from the point B.

Thus, using the formula Torque = Distance x Force acting

40x=70(40−x)

=> 40x=2800-70x

=> 70x-40x=2800

=> 30x=2800

=> x=2800/30

=> x=93.3333333
