Three force are applied to a square plane as shown in the figure. Find the modulus, direction and the point of application of the resultant force. If this point is taken on BC.

Q: Three force are applied to a square plane as shown in the figure. Find the modulus, direction and the point of application of the resultant force. If this point is taken on BC.

Numerical

(a) 2F, parallel to diagonal AC, at a distance (1/3)BC form B

(b) 2F, parallel to diagonal AC, at the mid –point of side BC

(c) 2√2F, parallel to diagonal AC, at a distance (2/3)BC form B

(d) √2F, parallel to diagonal AC, at a distance 1/3 BC form B

Ans: (b)
