Question

sappose ABCDEF are the vertices of a regular hexagon.Fine the resultant of the forces represented by the vectors AB,AC,AD,AE and AF

Answer 1

resultant force will be zero Becuz if O as a Centre pivot and thinking that all applied forces r equal ..
as we know that torque is equal to force into perpendicular distance.. so as perpendicular distance of AB AND AF r equal...so they will cancel out each other..then as PD of AC AND AE r equal so they too will cancel out each other...
as we know AD force is applied directly towards pivot do PD is zero so net force is zero
