Question

A windmill is pushed by four external forces as shown in the figure .Force F required to windmill still is-

Answer 1

Answer:

13N

Explanation: (10 X 2)+ (8 x 1) = (2 X F) + (2 X1)

(Wind mill will stop when force acting on opposite directions are equal)

Therefore 28 =2F + 2 ie 2F = 26 , ie F= 13 N
